Use the external public IP as the primary dns... as example for mydomain.com

 Have all the CNAMES for services point to the domain name, thus smtp or www
resolves to mydomain.com at the public IP.

Have the Linksys direct the open service ports, you should turn off DMZ if
the port forwarding is sufficient.

Get a friend, or another site or your isp, to be your primary/secondary
dns... be creative... exchange services...
