Hello Jason,

Thank you very much.

Yes I meant via eth0.

Thank you,

there's a list maintained for fedora core questions at:

        http://www.redhat.com/mailman/listinfo/fedora-list

i'm not trying to be a "mean guy" but this list has a tendency towards
being the dumping ground for all network-related linux questions, and
it's not.

your default gateway is set by the variable GATEWAY in:

        /etc/sysconfig/network

the GATEWAY variable can also be set in your:

        /etc/sysconfig/network-scripts/ifcfg-eth?
        
files.

if you specify it both places, RH used to have a tendency to add it
twice, i don't know if they've fixed this (by using 'ip route replace'
instead of 'ip route add').

i also hope you mean your default gateway is "via eth0" not "is eth0"
because if it's the latter--you've have bigger problems than just a
variable setting.
