I have had this problem on and off since RedHat 6, and I always
worked through
it, but I thought I would ask.
When you have multiple network interfaces, how does the system
determine the
default route?
Or is it the first, (or last) interface that comes up?

On the problem systems I have to add a "route add default..."
statement in
some systems in the rc.local to get them to work right.

GATEWAY is a bash variable - so whoever sets it last wins. I would recommend putting it in /etc/sysconfig/network .. I would also make sure that there are no files in /etc/sysconfig/networking or in /etc/sysconfig/networking/profiles/default .. these get read after the /etc/sysconfig/network-scripts files .. and as I mentioned before - whoever sets it last, wins.
