I have a VPN tunnel going from a TZ170 to a PRO 3060 and eveything seems okay at first. The tunnel is coming up green on both ends and I can ping from the TZ170 to the 3060. However, if I try to ping the other way it fails.
When I go into the diagnostics on the 3060 if I do a packet trace going from my computer behind the 3060 to the LAN address of the TZ170, it shows it as being successful. The logs on the 3060 are showing the ping as:
So it's like the ping is going out successfully but then on the return it's getting blocked by the 3060. I've tried making a rule to allow all communication from the TZ170, but it still fails.
I've also lowered the MTU and adjusted it to match on both sides, deleted and recreated the rule for the SA, etc, etc.
Can anyone tell me why the ping would fail but packet trace is showing successful? I need the tunnel to work both ways.. :)
