wrong default route

[Broekman, Maarten]

In general, having GATEWAY= lines in your ifcfg-eth* files is a bad
idea.  The default gateway should be specified in /etc/sysconfig/network
as Chet mentioned.  All the rest of the "gateways" are really just
static routes that you want to set up in a separate init script.

This might not be the only answer, but you could just specify GATEWAY=
192.168.65.142 in your /etc/sysconfig/network file and remove the
GATEWAY
definitions from all the ifcfg-eth* files.

>From there, I believe that if you want to override the GATEWAY
configured in
/etc/sysconfig/network, you can just re-add it in the specific
ifcfg-eth*
file, but in your case it doesn't seem like you want/need to do that.

Good luck!
