Weird IPSec VPN Tunnel issue What if you force UDP encapsulation (UDP/4500 instead of ESP), does the issue stop happening then? Is the FortiGate even receiving the missing packets in the problematic direction? (maybe the drop happens elsewhere?) Fortigate has an IPSec phase 1 bug since Hi, Ipsec uses UDP/500 and the protocol 50 (ESP) which cannot be NAT (Gnat Sartlink IPv4). Ipsec (Phase 2) Proposal Life Time (seconds): has to be 3600 . If the connection that the IPSec tunnels traverse down bounces, it's possible those sessions are taking the default routes instead of the routes specified to send those networks down the VPN interface. When the IPsec SA life is too Open the packet capture that is taken from initiator FortiGate using Wireshark, go to edit -> Preferences, Expand Protocol and look for ESP. 1 on the core switch.

So maybe start by checking what DH group NordVPN requires for ESP ("ipsec"). If you can set that to match, then you will probably succeed in re-negotiating a new ESP ESP seqno synced to primary FortiGate every five minutes, and big gap between primary and secondary to ensure that no packet is dropped after HA failover caused by tcp-replay. Normal internet connection is working fine. 168. Everything is normal, just like hundreds of other IPsec tunnels I manage on other FortiGates. Reply reply This subreddit has gone Restricted and reference-only There is an IPsec tunnel configured between fortigate and cisco IOS device.

Seems like something is blocking it, how do I figure this out? Yeah, my Fortigate refuses to make outbound connection attempts for the custom IPSEC tunnel types, only the wizards (afterwhich I can convert to a custom tunnel). Fortigate1 (WAN speed 1000Mbps up/down) Fortigate2 (WAN speed 200Mbps up/down) Without it, the Fortigate will route to the gateway of last resort when the vpn goes down and keep sessions there after the vpn comes back up. I have a Fortigate firewall configured with the standard interface MTU of 1500 and IPsec tunnel from the Fortinet negotiates an MTU of 1446, so I can only ping 1418 (data size) due to this limit. Both Fortigates will have 2 VIPs, 2 Policies, 2 SNAT (ippools), and 2 Static routes. The VPN connection should be in such a way that traffic from Internet Modem Fortinet will flow now set ipsec-soft-dec-async enable end ipsec-soft-dec-async is a software decryption asynchronization (using multiple CPUs to do decryption) for IPsec VPN traffic. By default this is L2TP/IPsec in Windows as well. Before that it required adjusting some files manually. In newer versions of FortiOS you can encapsulate the ESP header so it works through things like hotel and public networks. Moreover, a FortiGate doing "forced" NAT traversal means that the connecting client has no choice but to do NAT traversal with UDP encapsulation. Default route to the Fortigate. Check ESP sequence number synced on secondary FortiGate. For example, IIRC, Check Point only started supporting DPD in R81 by default. You can configure IPsec VPN in an HA environment using the GUI or CLI.

With basic IPsec no NAT is needed. 0/20) Destination: all NAT: Fragmentation is a killer for IPSec performance on the FortiGate because it forces those packets to be processed by the CPU instead of within the FortiASIC. If you know how, you can disable npu offloading(if your model has np), do a packet capture on IPsec interface and make sure you see clear text packet. I set the Local ID on the fortigate to 172. Permanently fix it by verifying there is a blackhole route for the ipsec remote subnets. I dont use IPSEC for dial-in users, only specific DDNS or Static hosts (other appliances) - Maintaining a trustedhost list in our local-in policy is easy enough in this case. 2 The other side is an ASA and they typically see around 200 log entries per hour, but during the time this issue is going on, their log entries pretty much drop to zero for the IPSEC logging.
