Accessing port forwarded application by external IP, from LAN
Hi,
I have successfully set up a port forward (!) for a service I run locally, that I need to access both at home and remotely. I am also using a dynamic DNS client to maintain a DNS setting for my external IP. From the outside, everything looks great - everything works - I can access the service by DNS name, and it connects properly.
When I'm on wifi at home, though, I cannot access the service by DNS name; my XB7 router appears to be filtering access to the port, when I try to access the WAN address from the LAN side.
On my old ASUS router, this was a non-issue, as it ran it's own DNS server, and would then provide the local IP as a DNS response to the domain name (e.g. from outside, the DNS name returned the WAN IP, but from inside the DNS name returned the LAN IP.)
The only solution I've come up with so far is to add a hosts file entry for the service, and disable that when I travel... which is okay for my laptop, but a real pain on my phone/tablet/etc.
Is there a better solution with the XB7? Did I do something wrong, inadvertently, to have this not work from the LAN side?

Here's the nmap output, when connected to the XB7 wifi:

AFAIK, the Comcast rented gateway devices do not support NAT loopback / hairpinnig.
