IPSec from pfSense 2.2.4 to Fortigate (don't know the version) flakey
I need help.
I have a client that has IPSec configured. One has a pfSense 2.2.4 box running on a NetGate ADI 2440 box. Single WAN. I have IPSec configured and mostly working L2L connected to a fortigate firewall managed by a third party.
IPSec phase 1 is configured to use mutual PSK, IKEv2, 3DES, SHA1, DH group 5. Both ends match.
The tunnels come up and I can ping from the pfSense side to a host in site B, and everything is working. People in site B can access what they need in site A. However, periodically, and I have not discovered what defines this periodicity, traffic from site B does not make it to the IPSec interface on pfSense. But if I ping my host in site B from site A, it responds like it should and traffic starts flowing again from site B.
This is maddening. I need suggestions, please.
Thanks in Advance

Check your phase 1 and phase 2 lifetimes, sounds like there is a mismatch.
