Thanks for the reply, however, I think this is a basic routing problem.
Essentially the issue is that I can't ping 192.168.2.200 when logged into 192.168.10.10
Both these systems are on networks connected to the router at 192.168.2.2 and 192.168.10.1 respectively. The router can ping everything and when I am logged into 192.168.2.200 I can ping 192.168.10.10.
The problem is though, when I am logged into 192.168.10.10 I can't ping 192.168.2.200.
