[buug] DNS help: tricking my network

[Brian Sobolak]

Hi

I've got the DSL working with a static IP.  This IP is
assigned to my Netgear firewall router, with ports 
punched open for HTTP, SSH, and DNS.  The ports are 
all forwarded to my FreeBSD box.

The problem is that when I try to access URLs that 
contain the domain I host I get an error.  The DNS 
server answers with the IP address from the public 
internet.  When the browser (for example) then tries 
to access this IP, the firewall answers.  Since the 
firewall is smart (sort of), it never routes the 
traffic to the public interface, and it never actually 
goes to the webserver.  I just get an error.

This usually isn't a problem - I just use the hostname 
or the private IP.  But some new software I installed 
uses fully qualified domains (e.g. 
www.planetshwoop.com/cgi-bin/foo.cgi instead of 
just /cgi-bing/foo.cgi) and it's causing a lot of 
frustration.

Can I set up the DNS server on my BSD box so that if 
it receives requests for domains that it hosts from 
the internal network it will give a different answer 
than requests from outside the private network?
