Ok, here's all the routers data in the configuration. Only DCconfig_internet is defined in my config file but I included everything just to be sure.

The machine only has one IP but it does have two names. It's original internal name was "route" but it now also has the name "mail". Eventually it'll have one name as I already have a router with a different name and IP. This one never actually routed anything, it was being prepared to do so until I got a better machine for routing. None of the routing systems are installed (iptables, etc.) so there's no firewall on this machine.

I haven't made any edits in this portion of the config file.
