Fully qualified domain name

[Alma J Wetzker]

Things are a bit crazy here so I haven't searched as much as I should have.

I have a Gentoo box that has a hostname but fails to pickup the domain name. 
I am using a generic belkin firewall/NAT router that assigns the IP using 
DHCP.  I have wetzker.org assigned as the domain in the router.

The real issue is that apache2 will not start without the FQDN and I need the 
web server running because I will be out of town and need access to my system.

Any ideas?   TIA
