DNS Tables need value for sites...

[HAL9OOO]

I have just installed a Watchguard SOHO 6 firewall\router for increased Internet security and all is working quite well except for the fact that any sites I host (internally) are not available to any systems behind the firewall. Watchguard states this is a drawback with their boxes (though, oddly enough, my cheaper Linksys performed this task flawlessly).

I am told that I simply need to populate the website names in the DNS Table so that port 80 traffic will be forwarded to the correct domain name (and, keep in mind, I host several different domains).

Does anyone know the correct procedure for doing this?

Thanks, in advance, for any assistance anyone can provide.
