default gateway causes IP failure

I have two nics, one public, one private. When GATEWAY is set in
/etc/sysconfig/network, default route is listed with 'route -n', but
network is unreachable. When I remove the GATEWAY value, restart
networking, and manually run 'route add default gw x.x.x.x', I am able to
ping both networks successfully. I am running on the 2.4.1 kernel.
Steps to Reproduce:
1. set GATEWAY=ISP gateway in /etc/sysconfig/network
2. '/etc/rc.d/init.d/network restart'
3. ping www.anything.org #ping fails
4. ping 10.1.1.4 #ping any public/private node/interface fails
5. comment GATEWAY=ISP_gateway in /etc/sysconfig/network
6. '/etc/rc.d/init.d/network restart'
7. 'route add default gw ISP_gateway
8. ping www.anything.org #ping any public/private node/interface succeeds
Actual Results: with the failed pings, I get no results at all until I
<ctrl>-C, then I get either one or no received packet(s). I don't even get
a "network unreachable' message during the ping.
Expected Results: ping replys
I assume that this is not the fault of routed, however, and assume it has
to do with the scripts that have been developed to access
/etc/sysconfig/network, however, I have little experience with c or script
programming, and do not know what script/process is calling the file. I am
not using X at all, and have made no changes through linuxconf, though I
have run it to see if there was something that I was missing.
I was able to ping with both values of GATEWAY set as per your example.
