Hi All,
I'm trying to configure a GRE tunnel on Sophos XG firewall appliance to connect to an extra IP block with various IP addresses.
I've followed various guides to configure the GRE tunnel via command line, and this works. If I do a wireshark I can see my pings to the external IP coming in on the WAN interface via the GRE tunnel.
However, this is where the problem occurs, the traffic is not going back through the GRE tunnel but via the regular WAN interface.
Can anyone tell me how I can force the traffic to go back through the GRE tunnel? To me, there is no interface that I can point to, and I need specific traffic to go through it.
