I have the following Problem:
Im trying to deploy a Sophos XG Firewall as a VM from Hetzner Online.
They give me /32 IP Adresses via DHCP.
Here´s a little example:
WAN -> IP: 123.123.123.213 - Netmask: 255.255.255.255 - Gateway: 172.31.1.1
LAN -> IP 10.10.0.2 - Netmask: 255.255.255.255 - Gateway: 10.10.0.1
Routing config from Hetzner Privat LAN: 0.0.0.0/0 (every IP that the Server wants to connect to)-> 10.10.0.1 (Hetzner GW) -> 10.10.0.2 (Sophos XG)
The Problem: If I try to make a Static Route in the XG for the Gateway LAN Interface, it says "The GW IP must be in the same Subnet as the LAN IP" -> But WHY???
I tested it with a PfSense and it worked fine. But I need to run a XG.
Anybody an idea?
