Here's something interesting.

When I run a traceroute to I get this:

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

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

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

[frankcox at audio network-scripts]$ ping
PING ( 56(84) bytes of data.
--- 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
