I recently got a domain...www.mydomainname.com for discussion purposes.
This domain points to the external public ip of my firebox and port 80
is nated throught to an internal web server. If I browse to
http://www.mydomainname.com from a computer outside my firewall
everything is ok, but If I browse to it from a computer within the
network it does not work. I think this has to do with "loopback" but
I'm not sure. In the traffic monitor on the firefox it shows something
like this when I try to browse from the internal pc:

05/16/06 10:06 http-proxy[4395]: [<int ip here>:1662 <ext ip
here>:80] Error while sending/receiving: Can't receive data from server
(Connection refused)

The tracert from the internal pc looks like this:

Tracing route to www.mydomainname.com [<ext ip here>]
over a maximum of 30 hops:

1 <1 ms <1 ms <1 ms <ext ip here>.something.so.so.net [<ext
ip here>]

Trace complete.

On a linksys router I just have to uncheck "Internet NAT redirection"
and everything is fine, but I don't know what to do on a firebox.


Thanks!

I've never seen "loopback" work on any Firebox, and I don't even think
it's an option. I've put in about 80 of them over the last couple years
and always used an internal DNS server to resolve the public names to
the local network addresses so that it never has to loopback.
