Special routing.

I am currently facing the exact same issue as johann also at an online.net server.

I was hoping someone here might have some additional insight.

I cannot configure the IP on the interface without a gateway (and to add a route afterwards) as XG requires me to set a gateway.

There is another thread around: https://community.sophos.com/products/xg-firewall/f/network-and-routing/73190/wan-ip-and-gateway-ip-not-in-same-network-error which has the same problem, unfortunately also that one does not lead to success for me.
