Ok, so I have a FreeBSD box that is running ipfw and nat which accepts 
traffic on port 80 just fine on both inside and outside interfaces.
I have a port redirect that takes http requests on port 5040 and 
shoots them to an internal web server. this works fine from the outside 
but does not from the inside. Why?
example: If 192.168.1.3 types http://192.168.0.1:5040 into their 
browser it doesn't connect.
But if 192.168.0.2 types http://192.168.0.1:5040 it works like a charm.
I have looked for other posts on this topic but all I have found 
is some business about running two copies of natd and some other 
stuff about training my users to type in the inside address when 
on the inside and the outside address when at home. I don't want 
a split DNS either. Where is the elegant solution that I'm looking 
for...like "just do a route add blah blah blah..."
