VPN IPsec - no traffic when FEC enabled on both sides

[Vince_Forti]

Hi everyone,

I have an issue I can't understand. Explanation :  I have a dialup tunnel ipsec vpn between two fortigates (one with fortios and one with forti100( dialup client) ). Everything is fine. I have activated FEC  on the fortios side, everything is fine.

My issue is when i activate FEC (egress and ingress) on the forti100 side, the tunnel is up but no traffic passes. Question : is activating FEC (forward correction error) on both sides a good idea ?

Thank you !

Best regards

Vincent

What image version are you using? There are currently some issues with FEC, which may cause the device to crash.

Hello Kangmin,

FortiOS with FEC ok : v6.4.6 build1879 (GA)

Fortigate 100E with FEC crashing only the traffic ipsec : v6.4.6 build1879 (GA)

Thank you,

Best regards,

Vincent
