I'm trying to setup a Site2Site tunnel and it seems "half" working.
For now I'll only troubleshoot one side of the connection:
The remote side is 10.40.171.0/26
Local side is: 10.30.171.0/26
10.40.171.5 can wget a http page on 10.30.171.62 but cannot ping it.
My firewall which has the directional matching for this site2site is allowing all and I can see the ping coming in. And tcpdump on 10.30.171.62 also sees it, but the reply doesn't seem to come back to 10.40.171.5
However, if I turn off vpn accel (vpn accel off) - it works. And I'm not sure why.
