I had a similar situation a couple of days ago. Running
redhat-config-network and adding the gateway there didn't help any too
since as soon as I'd finish adding the gateway and doing a
"/etc/rc.d/init.d/network restart" my gateway would disappear again.

In the end I added the line GATEWAY=xxx.xxx.xxx.xxx to the
/etc/sysconfig/network file by hand and that seemed to fix it.

HTH,
