Here's something interesting.

When I run a traceroute to 204.83.15.254 I get this:

[frankcox at audio ~]$ traceroute 204.83.15.254
traceroute to 204.83.15.254 (204.83.15.254), 30 hops max, 40 byte packets
 1   (204.83.15.1)  3000.077 ms !H  3000.068 ms !H  3000.052 ms !H

It thinks that 204.83.15.254 is down, and that's the gateway address for eth1 that I want to be the default gateway.

And 192.168.1.1 is the address of the router that eth0 is plugged into:

[frankcox at audio network-scripts]$ ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
--- 192.168.1.1 ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 1999ms

I can ssh into the server through that router (and eth0) with no problem.  That's how I'm communicating with it right now.

[frankcox at audio network-scripts]$ /sbin/route -n
