My LAN is on 10.0.0.0/8 and I've been given a small block of IP addresses and a gateway address by my ISP (WAN addresses). The problem is that the gateway address given to me is not in the 10.0.0.0/8 subnet. So I want, for example, 10.0.1.1 to use the default gateway of, say, 126.96.36.199 (a WAN address) but because they're not on the same subnet, it's not working. But they are attached to the same switch, so they can physically contact each other - I can ping the WAN address from the LAN, no problem. Is there a way to specify - on Ubuntu - that the LAN is 10.0.0.0/8 + the default gateway WAN address? Or set the default route manually so that it'll send to the WAN?
