[Mailman-Developers] Using the correct host

I've been trying to set up a list behind my firewall on the local network. The machine hosting mailman uses 192.168.0.2 as a static IP, but the world sees me as ernest.isa-geek.org, the DNS entry I got through dyndns.org.

If you try to subscribe to the list I created, the subscribe button sends the request to 192.168.0.2 instead of ernest.isa-geek.org. While that works fine from here, people out there aren't having any luck.

How do I make the subscribe button use the dns name vs the IP?

You can see what I'm talking about by going here and trying to subscribe to the list:

I just noticed that the listinfo page says that there "currently are no publicly-advertised Mailman mailing lists on www.ernest.isa-geek.org". How do I make the list publicly-advertised?
