Tunnel between 2 Sophos XG

GernotMeyer

Hi,

we have 2 XG Systems (both 18.4). There is a Tunnel that stops working sometimes between both.Tunnel shows "up"!

There is no error in system log.

FW log from sender logs the packets but they are not arrive on the target.

Tunnel off and tunnel on and it's all fine again.

Any idea how to solve this? Where to search for hints?

Because tunnel down and up solves the data flow I guess it should be one of the Sophos XGs. Or not?

Thanks for hints!

    You can check on both appliances the drop packet capture and the tcpdump. Does any of both appliances drop the packets or use the wrong route? 

    BEcause if you restart the tunnel, it sounds like the route is not applied and traffic will be routed differently.
