IPSec Site to Site VPN - no traffic

Hi,

I am trying to configure site to site VPN between an Sophos UTM 9.006_5 on site "A" against a WatchGuard on site "B".

Right after the initial configuration, I was able to ping an IP address on the remote subnet. The day after it stopped and has never worked ever since.

Nothing was changed on the Astaro and the "other guy" claims nothing was changed on the WatchGuard. 

Both firewalls shows the tunnel is up, but neither can ping to the other side.

I am quite sure all parameters for main and quick mode is correct (checked multiple times) but I cannot seem to spot the problem.

I enabled debug logging and collected this log from the ASG. Hope someone can provide some input.

Thx.

  • If both sides have correctly indicated the subnets in the tunnel, then the only thing I can think of is that pinging is regulated on the 'ICMP' tab of 'Firewall' in WebAdmin.

    Cheers - Bob
