On some FortiGate units, such as the FortiGate 94D, you cannot ping over the IPsec tunnel without first setting a source-IP. If you want to bounce a particular VPN Tunnel run the following command, dia vpn ike gateway flush name %Tunnel-Name%. Ensure that your FortiGate unit is in NAT/Route mode, rather than Transparent. Connecting the FortiGate to the RADIUS server. This section contains tips to help you with some common challenges of IPsec VPNs. Use the execute ping command to ping the Cisco device public interface. Here is a list of common problems and what to verify. After each attempt to start the L2TP over IPsec VPN, select. Depending on the Remote Gateway and Authentication Method settings, you have a choice of options to authenticate FortiGate dialup clients or VPN peers by ID or certificate name (see Phase 1 parameters on page 46). When a device with NAT capabilities is located between two VPN peers or a VPN peer and a dialup client, that device must be NAT traversal (NAT-T) compatible for encrypted traffic to pass through the NAT device. Tag: firewall, Security. A green arrow means the tunnel is up and currently processing traffic. I am going to describe some concepts of IPSec VPNs. Session is part of Ipsec tunnel (from the originator) re. Save my name, email, and website in this browser for the next time I comment. To configure an IPSec VPN to a ZIA Public Service Edge: Review the supported IPSec VPN parameters; Add VPN credentials in the Admin Portal; Link the VPN credentials to a location; Configure your edge router or firewall to forward traffic to the Zscaler service. If a duplicate instance of the VPN tunnel appears on the IPsec Monitor, reboot your FortiGate unit to try and clear the entry. If the packet was encrypted correctly using the correct key, then the decryption will be successful and it will be possible to see the original package as shown below: Repeat the decryption process for the packet capture from the recipient firewall. If you have determined that your VPN connection is not working properly through Troubleshooting on page 223, the next step is to verify that you have a phase2 connection. (IP address or modified). Enter the following command to reset debug settings to default: Enter the following CLI command diagnose sniffer packet any icmp 4. In general, begin troubleshooting an IPsec VPN connection failure as follows: General troubleshooting tips. When I started doing VPN way back and there were filters set up, I would be dumbfounded at why I was not receiving any traffic from a particular gateway. Today we will cover basic FortiGate IPsec Troubleshooting. These commands are typically used by Fortinet customer support to discover more information about your FortiGate unit and its current configuration. Check the security policies. ; Set the User Type to Local User and click Next. Check that the encryption and authentication settings match those on the Cisco device. When the management IP address is set, access the FortiGate login screen using the new management IP address. If one end of an attempted VPN tunnel is using XAuth and the other end is not, the connection attempt will fail. For example, on some models the hardware switch interface used for the local area network is called lan, while on other units it is called internal. The FortiGate can send a GRE keepalive response to a Cisco device to detect a GRE tunnel. Confirm that the user is a member of the user group assigned to L2TP. Alternatively, you can enter netplwiz. The options to configure policy-based IPsec VPN are unavailable. There are two Fortigate HA modes available: Active / Passive- Configuration of primary and secondary devices are in synchronisation. Above you can see the different filtering criteria. In the following example, the error message was seen on the recipient FortiGate: date=2010-12-28 time=18:19:35 devname=Kosad_VPN device_id=FG300B3910600118 log_ id=0101037132 type=event subtype=ipsec pri=critical vd=root msg=IPsec ESP action=error rem_ ip=180.87.33.2 loc_ip=121.133.8.18 rem_port=32528 loc_port=4500 out_intf=port2 cookies=88d40f65d555ccaf/05464e20e4afc835user=N/A group=N/A xauth_user=N/A xauth_ group=N/A vpn_tunnel=fortinet_0 status=esp_error error_num=Invalid ESP packet detected (HMAC validation failed). It is not complete nor very detailled, but provides the basic commands for troubleshooting network related issues that are not resolvable via the GUI. If the ping or traceroute fail, it indicates a connection problem between the two ends of the tunnel. Troubleshooting IPSec VPNs on Fortigate Firewalls. The first diagnostic command worth running, in any IPsec VPN troubleshooting situation, is the following: diagnose vpn tunnel list. Open the packet capture that is taken from initiator FortiGate using Wireshark. Establishing the connection in this manner means the local FortiGate will have its configuration information as well as the information the remote computer sends. Here we can see the platform connecting to/from. The output will show packets coming in from the GRE interface going out of the interface that connects to the protected network (LAN) and vice versa. ESP can be used with confidentiality only, authentication only, or both confidentiality and authentication. The Fortinet Cookbook contains examples of how to integrate Fortinet products into your network and use features such as security profiles, wireless networking, and VPN. For users connecting via tunnel mode, traffic to the Internet will also flow through the FortiGate, to apply security scanning to this traffic. This site uses Akismet to reduce spam. Internet Key Exchange or IKE Is the mechanism by which the two devices exchange the keys. This single VPN tunnel will have only one phase 1 (IKE) tunnel / security association and again only one single phase 2 (IPsec) tunnel / SA. Did you create an ACCEPT security policy from the public network to the protected network for the L2TP clients? This allows you to filter a VPN to a destination of 2.2.2.2 as an example: diagnose vpn ike log-filter dst-addr4 2.2.2.2. Rashmi Bhardwaj The Fortinet Cookbook contains examples of how to integrate Fortinet products into your network and use features such as security profiles, wireless networking, and VPN. Phase I The purpose of phase 1 is to establish a secure channel for control plane traffic. Session is intercepted by wccp process. The plethora of vendors that resell hardware but have zero engineering knowledge resulting in the wrong hardware or configuration being deployed is a major pet peeve of Michael's. The diagnostics command is available via the nsdiag command in both Microsoft Windows and macOS devices. Make sure that both VPN peers have at least one set of proposals in common for each phase. This is intended as a quick-tip but I have another article that dives a little deeper into the PSK errors etc. This blog post is a list of common troubleshooting commands I am using on the FortiGate CLI. wccp. FortiGate models differ principally by the names used and the features available: Naming conventions may vary between FortiGate models. Notify me of follow-up comments by email. The command is diagnose vpn ike log-filter dst-addr4 10.11.101.10. For example, on some models the hardware switch interface used for the local area network is called. It is possible to identify a PSK mismatch using the following combination of CLI commands: diag vpn ike log filter name diag debug app ike -1 diag debug enable. By: Aug 11, 2022. If this appears to be the case, configure a DHCP relay service to enable DHCP requests to be relayed to a DHCP server on or behind the FortiGate server. l Check that a static route has been configured properly to allow routing of VPN traffic. To configure a multicast policy, use the config firewall multicast-policy. For debugging purposes, sometimes it is best for all the traffic to be processed by software. Here we can see that Quick-Mode has failed. Configure the management interface. FortiOS allows L2TP connections with empty AVP host names and therefore Mac OS X L2TP connections can connect to the FortiGate. config sys global set ipsec-asic-offload [enable | disable] end. Since last week, we observed a lot of failed SSL-VPN login events on various FortiGate setups. The remote client must have at least one set of Phase 2 encryption and authentication algorithm settings that match the corresponding settings on the FortiGate unit. FW-01 # get vpn ipsec tunnel name VPN- gateway name: 'VPN-' type: route-based local-gateway: 199.26.76.158:0 (static) In this example, you will allow remote users to access the corporate network using an SSL VPN, connecting either by web mode using a web browser or tunnel mode using FortiClient. See Troubleshooting L2TP and IPsec on page 232. (Edit: That was back in August of 2021 and the big scanning ended around two weeks after it has started. For IPsec VPNs, Phase 1 and Phase 2 authentication and encryption events are logged. I am not focused on too many memory, process, kernel, etc. details. ; Enter the Username (client2) and password, then click Next. Go to Edit > Preferences, expand Protocol and look for ESP. See Troubleshooting GRE over IPsec on page 235. Troubleshooting Commands: Fortigate HA. ; Enter all information about your LDAP server. For example, on some models the hardware switch interface used for the local area network is called lan, while on other units it is called internal. During the connecting phase, the FortiGate will also verify that the remote users antivirus software is installed and up-to-date. br. You can use the diagnose vpn tunnel list command to troubleshoot this. Using the Cookbook, you can go from idea to execution in simple steps, configuring a secure network for better productivity with reduced risk. Phase 1 can operate in two modes: main and aggressive. Authentication Header or AH The AH protocol provides authentication service only. Similar to the Phase-1 command, you can list the Phase-2 information about the tunnel. If the ping or traceroute fail, it indicates a connection problem between the two ends of the tunnel. AH authenticates IP headers and their payloads, with the exception of certain header fields that can be legitimately changed in transit, such as the Time To Live (TTL) field. To allow VPN traffic between the Edge tunnel interface and the Branch tunnel interface, go to VPN > IPsec Tunnels, and edit the VPN tunnel. This section describes some checks and tools you can use to resolve issues with the GRE-over-IPsec VPN. Using the Cookbook, you can go from idea to execution in simple steps, configuring a secure network for better productivity with reduced risk. To configure an SSL VPN server in tunnel and web mode with dual stack support in the GUI: Create a local user: Go to User & Authentication > User Definition and click Create New.The Users/Groups Creation Wizard opens. At the conclusion of phase 2 each peer will be ready to pass data plane traffic through the VPN. A red arrow means the tunnel is not processing traffic, and this VPN connection has a problem. The following section provides information to help debug an encryption key mismatch. Troubleshooting Tip: IPsec VPNs tunnels. Maybe this will meet my needs: TP-Link SafeStream TL-ER604W Wireless N300 Gigabit Broadband Desktop VPN Router, 120M NAT throughput, 10k Concurrent Sessions, 256 DHCP Clients, 20 VPN Tunnels You may not want to bounce the tunnel, but you may want to clear the counters on the tunnel so you could see encrypts and decrypts. And finally, Some remote firewalls such as Cisco, do not like Fortinet/Palo/Checkpoint etc groups on Phase II Selectors. Virtual switch support for FortiGate 300E series 6.2.2 IPsec VPN wizard hub-and-spoke ADVPN support 6.2.2 FortiGuard communication over port 443 with HTTPS 6.2.2 IPv6 FortiGuard connections 6.2.2 SSH file scan 6.2.2 Michael Pruett, CISSP has a wide range of cyber-security and network engineering expertise. Lets start with a little primer on IPSec. Furthermore, in circumstances where multiple remote dialup VPN tunnels exist, each tunnel must have a peer ID set. The command is located in the Client installation directory: The ESP packet invalid error is due to an encryption key mismatch after a VPN tunnel has been established. NPU offloading is supported when the local gateway is a loopback interface. diagnose vpn ike log-filter dst-addr4 %Peer-IP%, Then we are going to start debugging IKE and the -255 is the verbosity (another useful one is -1, My proposal This tells you what your firewall is offering as a Phase 1. Pre-shared Key authentication is successful. Because of this, you would not see this error. Today we will cover basic FortiGate IPsec Troubleshooting. Stop any diagnose debug sessions that are currently running with the CLI command diagnose debug disable, Clear any existing log-filters by running. If you get audited, they WILL ding you on this. Ensure that both ends of the VPN tunnel are using Main mode, unless multiple dial-up tunnels are being used. combination in their settings. The Fortinet Cookbook contains examples of how to integrate Fortinet products into your network and use features such as security profiles, wireless networking, and VPN. Select Attempt to detect/decode encrypted ESP payloads, and fill in the information for the encryption algorithm and the keys. This shows us Phase I is up. Check the encapsulation setting: tunnel-mode or transport-mode. A 1500 byte MTU is going to exceed the overhead of the ESP-header, including the additional ip_header,etc. Enter control userpasswords2 and press Enter. There are two Fortigate HA modes available: Active / Passive- Configuration of primary and secondary devices are in synchronisation. Essentially, you would see 10.x.x.x/24 on one side but the other configured as 192.168.0.0/24 as an example. A number of features on these models are only available in the CLI. Attempt to use the VPN and note the debug output in the SSH or Telnet session. If you do not know the other ends settings enable or disable XAuth on your end to see if that is the problem. If the connection is properly configured, a VPN tunnel will be established automatically when the first data packet destined for the remote network is intercepted by the FortiGate unit. Another appropriate diagnostic command worth trying is: diagnose debug flow. High Availability Palo Alto. I am going to describe some concepts of IPSec VPNs. config system settings set multicast-forward enable. The first diagnostic command worth running, in any IPsec VPN troubleshooting situation, is Check the logs to determine whether the failure is in Phase 1 or Phase 2. Otherwise use IP addresses. Remove any Phase 1 or Phase 2 configurations that are not in use. Session is attached to local fortigate ip stack. A continuacin se encuentra una seleccin de comandos tiles para solucionar los problemas ms comunes va el CLI de Fortigate. See Phase 1 parameters on page 46. When the management IP address is set, access the FortiGate login screen using the new management IP address. Traceroute the remote network or client. Using the Cookbook, you can go from idea to execution in simple steps, configuring a secure network for better productivity with reduced risk. Without a match and proposal agreement, Phase 1 can never establish. diagnose debug app ike 255 diagnose debug enable. Take a packet sniffer trace on both FortiGates. If the management interface isnt configured, use the CLI to configure it. Lets start with a little primer on IPSec. Testing Phase 1 and 2 connections is a bit more difficult than testing the working VPN. A VPN connection has multiple stages that can be confirmed to ensure the connection is working properly. All messages in phase 2 are secured using the ISAKMP SA established in phase 1. See Phase 1 parameters on page 46 and Phase 1 parameters on page 46. Cisco would make you create separate Phase II selectors. During the connecting phase, the FortiGate will also verify that the remote users antivirus software is installed and up-to-date. The Fortinet Cookbook contains examples of how to integrate Fortinet products into your network and use features such as security profiles, wireless networking, and VPN. Session is bridged (vdom is in transparent mode) redir. To configure the SSL VPN tunnel, go to VPN > SSL-VPN Settings. This command should only be used for testing, troubleshooting, maintenance, and demonstrations. If the endpoint is not managed by EMS, proceed to step 2. type=INTEGR, val=AUTH_HMAC_SHA_2_256_128 type=PRF, val=PRF_HMAC_SHA2_256 type=DH_GROUP, val=1536. FortiGate models differ principally by the names used and the features available: Naming conventions may vary between FortiGate models. If this happens, try removing some of the unused proposals. Configuring the SSL VPN tunnel. The resulting output may indicate where the problem is occurring. ; Select Test Connectivity to be sure you can connect to the RADIUS server. For example, on some models the hardware switch interface used for the local area network is called lan, while on other units it is called internal. AH-style authentication authenticates the entire IP packet, including the outer IP header, while the ESP authentication mechanism authenticates only the IP datagram portion of the IP packet. To configure the LDAP service, go to User & Device > LDAP Servers and select Create New. Use Config Global Mode. protocol = IKEv2: encapsulation = IKEv2/none type=ENCR, val=AES_CBC (key_len = 128) type=INTEGR, val=AUTH_HMAC_SHA_96 type=PRF, val=PRF_HMAC_SHA type=DH_GROUP, val=1536. Finally the error telling you no matching Phase II found. Having both sets of information locally makes it easier to troubleshoot your VPN connection. Usually they are quick easy commands to make your day brighter and help you finish up quicker so you can enjoy family, friends, and libations. Incoming proposal This tells you what the remote gateway is sending you as Phase 1. This kind of information in the resulting output can make all the difference in determining the issue with the VPN. The error saying that the Phase II selector was the issue. You can confirm this by going to Monitor > IPsec Monitor where you will be able to see your connection. ; Certain features are not available on all models. Authentication OK. The table below is a list of common L2TP over IPsec VPN problems and the possible solutions. In this output, we do not see a specific PFS error, but normally in Phase II these are the following situations you will find: In route-based VPNs we normally use 0.0.0.0/0 as the Phase II selectors. type=INTEGR, val=AUTH_HMAC_SHA_96 type=PRF, val=PRF_HMAC_SHA type=DH_GROUP, val=1536. get system ha status > IPSec VPN Configuration: Fortigate Firewall. To filter out VPNs so that you focus on the one VPN you are trying to troubleshoot. If the endpoint is currently managed by EMS, do the following: The EMS administrator deregisters the endpoint. Check Phase 1 configuration. Port 1 is the management interface. Under Phase 2 Selectors, create a new Phase 2. Quick-Tips are short how tos to help you out in day-to-day activities. In this scenario, you could have AES-256 SHA-256 but it not be configured on the other side. Use the FortiGate VPN Monitor page to see whether the IPsec tunnel is up or can be brought up. A successful negotiation proposal will look similar to, IPsec SA connect 26 10.12.101.10->10.11.101.10:500 config found created connection: 0x2f55860 26 10.12.101.10->10.11.101.10:500 IPsec SA connect 26 10.12.101.10->10.11.101.10:500 negotiating no suitable ISAKMP SA, queuing quick-mode request and initiating ISAKMP SA negotiation initiator: main mode is sending 1st message, cookie 3db6afe559e3df0f/0000000000000000 out [encryption], sent IKE msg (ident-i1send): 10.12.101.10:500->10.11.101.10:500, len=264, id=3db6afe559e3df0f/0000000000000000. For this example, default values were used unless stated otherwise. Both devices must use the same mode. Using the Cookbook, you can go from idea to execution in simple steps, configuring a secure network for better productivity with reduced risk. responder received SA_INIT msg incoming proposal: protocol = IKEv2: encapsulation = IKEv2/none type=ENCR, val=AES_CBC (key_len = 256). A mismatch could occur for many reasons, one of the most common is the instability of an ISP link (ADSL, Cable), or it could effectively be any device in the physical connection. Rashmi Bhardwaj Troubleshooting L2TP and IPsec. If the decryption failed using the same key, the packet may be corrupted and the interface should then be checked for CRC or packet errors. Remote access IPSec VPNs use aggressive mode. Transport Mode Transport Mode provides a secure connection between two endpoints as it encapsulates IPs payload. Alert email can be configured to report L2TP errors. You can configure the FortiGate unit to log VPN events. It may occur once indicating a successful connection, or it will occur two or more times for an unsuccessful connection there will be one proposal listed for each end of the tunnel and each possible Troubleshooting connection issues. See Phase 1 parameters on page 46. This makes the remote FortiGate the initiator and the local FortiGate becomes the responder. This will provide you with clues as to any PSK or other proposal issues. The Fortinet Cookbook contains examples of how to integrate Fortinet products into your network and use features such as security profiles, wireless networking, and VPN. The VPN tunnel initializes when the dialup client attempts to connect. In this section, I removed PFS on one side of the VPN. The resulting output should include something similar to the following, where blue represents the remote VPN device, and green represents the local FortiGate. Prior to FortiOS 4.0 MR3, FortiOS refused L2TP connections with empty AVP host names in compliance with RFC 2661 and RFC 3931. Troubleshooting Commands: Fortigate HA. To confirm that a VPN between a local network and a dialup client has been configured correctly, at the dialup client, issue a ping command to test the connection to the local network. Optionally, set Restrict Access to Limit access to specific hosts and specify the addresses of the hosts that are allowed to connect to this VPN. This may or may not indicate problems with the VPN tunnel, or dialup client. The following section includes troubleshooting suggestions related to: l LAN interface connection l Dialup connection l Troubleshooting VPN connections l Troubleshooting invalid ESP packets using Wireshark l Attempting hardware offloading beyond SHA1 l Check Phase 1 proposal settings l Check your routing l Try enabling XAuth. Ping the remote network or client to verify whether the connection is up. enc: spi=c32b09f7 esp=3des key=24 0abd3c70032123c3369a6f225a385d30f0b2fb1cd9687ec8 ah=sha1 key=20 214d8e717306dffceec3760464b6e8edb436c6 This is the packet capture from the FortiGate: To verify, it is necessary to decrypt the ESP packet using Wireshark.

Here is an example of a route-based VPN configured on a Palo Alto Networks firewall. ; Optionally, configure the contact In this example, I left ONLY AES-128 SHA256while the remote firewall had the AES-128 SHA256removed causing a mismatch. diag debug app ike -1 diag debug enable. Enter the following CLI commands diagnose debug application ike -1 diagnose debug enable. Watch the screen for output, and after roughly 15 seconds enter the following CLI command to stop the output. For more information, see Feature visibility. The most common IPsec VPN issues are listed below. The log messages for the attempted connection will not mention XAuth is the reason, but when connections are failing it is a good idea to ensure both ends have the same XAuth settings. ; Certain features are not available on all models. The remote client must have at least one set of Phase 1 encryption, authentication, and Diffie-Hellman settings that match corresponding settings on the FortiGate unit. handshake between the ends of the tunnel is in progress. This will allow you to review the data later on at your own speed without worry about missed data as the diag output scrolls by. (Edit: That was back in August of 2021 and the big scanning ended around two weeks after it has started. In this scenario, you must assign an IP address to the virtual IPsec VPN interface.

Have you ever installed a Windows server to do Full Story, Why would you need to export the private key Full Story, I had a customer that installed a wildcard certificate Full Story, 2021 InfoSec Monkey | Design by Fitser, peer proposal is: peer:0:10.3.39.0-10.3.39.255:0, me:0:10.1.0.0-10.1.255.255:0, Querying Nested LDAP Groups on the FortiGate, Quick-Tip : How To Run Sniffer on FortiGate CLI. Web mode allows users to access network resources, such as the the AdminPC used in this example. Set the log-filter to the IP address of the remote computer (10.11.101.10). See Troubleshooting L2TP and IPsec on page 232. For example if 10.11.101.10 selected both Diffie-Hellman Groups 1 and 5, that would be at least 2 proposals set. When an IPsec VPN tunnel is up, but traffic is not able to pass through the tunnel, Wireshark (or an equivalent program) can be used to determine whether there is an encryption mismatch. If there are many proposals in the list, this will slow down the negotiating of Phase 1. Routing problems may be affecting DHCP. When you are finished, disable the diagnostics by using the following command: diagnose debug reset diagnose debug disable. This recipe is in the Basic FortiGate network collection. diaike 0: comes 10.12.101.1:500->10.11.101.1:500,ifindex=26. If you can determine the connection is working properly then any problems are likely problems with your applications. Set up the commands to output the VPN handshaking. config system gre-tunnel edit set keepalive-interval set keepalive-failtimes . Certain features are not available on all models. Select complementary mode settings. If you are using FortiClient, ensure that your version is compatible with the FortiGate firmware by reading the FortiOS Release Notes. Start an SSH or Telnet session to your FortiGate unit. Select Convert To Custom Tunnel. This filters out all VPN connections except ones to the IP address we are concerned with. Because you have installed FSSSO in advanced mode, you need to configure LDAP to use with FSSO. This recipe is in the Basic FortiGate network collection. Using the output from Obtaining diagnose information for the VPN connection CLI, search for the word proposal in the output. FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic. However if not: Have you ever installed a Windows server to do Full Story, Why would you need to export the private key Full Story, I had a customer that installed a wildcard certificate Full Story, 2021 InfoSec Monkey | Design by Fitser, Route-Based VPN between Cisco Router and Fortigate Firewall using OSPF. Anything sourced from the FortiGate going over the VPN will use this IP address. This section shows it is receiving AES 128 with a Hash of SHA 256, Shows that we matched a particular VPN we have configured and it matches what I created. Check the routing behind the dialup client. For more information, see Phase 1 parameters on page 46. This section includes: Quick checks l Mac OS X and L2TP; Setting up logging; Using the FortiGate unit debug commands; Quick checks. This is intended as a quick-tip but I have another article that dives a little deeper into the PSK errors etc. Encapsulating Security Payload or ESP The ESP protocol provides data confidentiality by using encryption and authentication (data integrity, data origin authentication, and replay protection). Uninstalling FortiClient. Create the VPN tunnels of interest or receive the VPN list of interest from FortiClient EMS. You can also use it as a standalone recipe. Much like NPU-offload in IKE phase1 configuration, you can enable or disable the usage of ASIC hardware for IPsec Diffie-Hellman key exchange and IPsec ESP traffic. See Phase 1 parameters on page 46 and Phase 2 parameters on page 66.
