I'm feeling a bit stupid because this seemingly simple task is completely stumping me.
I have 3 PCs: Client, Gateway and Server.
Client needs to connect via Gateway to Server.
Both PCs are connected to gateway via crossover cables.
Static IPs have been given to each interface.
Client:eth1 ip : 192.168.138.1\24 gateway 192.168.138.254 Gateway eth4 ip 192.168.138.254\24 gateway 192.168.138.1 Gateway eth1 ip 192.168.137.254\24 gateway 192.168.137.1 Server eth0 ip 192.168.137.1\24 gateway 192.168.137.254
Client can ping Gateway eth4 and eth1, Server can ping Gateway eth4 and eth1 but Client cannot ping Server.
Gateway can ping everything.
At first I thought I needed to insert static routes on Client and Server but this did not help and I now think that as they can ping the Gateway interface on the other network it is not necessary?
