There should only be one default gateway entry. If you have multiple entries, and you then relocate the system so it has a different gateway, then you have to locate and change *every* applicable entry. With only one entry in a standard location, a single update handles the change. If your system is acting as a gateway router for other systems on your local network there are different issues involving static routes. For a workstation on 2 different networks, only one default gateway can be used. > TYPE=Ethernet > USERCTL=no > IPV6INIT=no > PEERDNS=yes > MTU=9000 > > Internal traffic from the server goes out eth1 since that route gets > tried before the default route. > > Cheers, > Dave > > -- > Politics, n.
