You're a lifesaver! I've been pulling my hair out for since yesterday
Yeah, I shouldn't have displayed my IP's (I don't have ftp or telnet; I have SSH and I have set AllowUsers in the config to my name. I also don't allow root logins) since that is information that attackers can use!

So you were right! The dhcp server running on the router plugged into my second interface was overwriting everything. I looked up the manpage of dhclient.conf and found a few howtos. I forced the default router to be 209.x.y.54 and that seemed to work! Here's my dhclient.conf:

backoff-cutoff 2;
initial-interval 1;
retry 10;
select-timeout 0;
timeout 30;

interface "vr0" {
   supersede routers 209.x.y.54;
   supersede host-name "enterprise";
   supersede domain-name "xxxx.xxx";
   request subnet-mask,
           domain-name-servers;

   require subnet-mask,
           domain-name-servers;
}

Once again, thanks a whole bunch!
