If I add:- $ route add default gw 10.0.0.1 ... I get a gateway on eth1 and my routing table becomes:- $ route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default 10.0.0.1 0.0.0.0 UG 0 0 0 eth1 default 10.1.0.1 0.0.0.0 UG 0 0 0 eth0 10.0.0.0 * 255.255.0.0 U 0 0 0 eth1 10.1.0.0 * 255.255.0.0 U 0 0 0 eth0 ... and then I *can* ping out on eth1. So for a *dual* Ethernet system, how do I get both default gateway entries using ifup / ifdown / etc ?
