3800HGV-B Gateway router loopback workaround?

I have a 3800HGV-B Gateway as part of AT&T Uverse install. I just discovered it does not have loopback.

I have multiple port ranges forwarding to multiple IPs on the LAN:
Ex: 2000-2010 to 192.168.1.100, 2020-2030 to 192.168.1.101, etc.

I reference the public IP address as mycompany.dyndns.org.

From outside the LAN, all is well.

From inside the LAN, can you think of a workaround that would allow me to make mycompany.dyndns.org:2001 go to 192.168.1.100:2001 and mycompany.dyndns.org:2021 to 192.168.1.101:2021?

By the way, the 3800HGV-B Gateway address is 192.168.1.254 and when I try accessing 192.168.1.254:2001 I do NOT get forwarding to 192.168.1.100:2001 (just in case someone thought of suggesting remapping my hosts file to the gateway).

Hope you guys have some workaround (right now I can only think of a VPN, and giving up dyndns for addressing)

Thanks

I don't think what you're asking is possible. At least not the way you describe above.  The reason is that you are using the same DNS name  (mycompany.dyndns.org) for for both. DNS is going to map that name to the same IP address, regardless of the port specified.  You can have more than 1 address for that name in DNS but you can't control which one it uses. It will use each alternately in a round robin fashion.

I think you would need a unique name for each IP.

Thank you for the confirmation.

I was basically hoping for a miracle somehow, but no such thing. I'll just have to set up a VPN and refer to the computer's name directly instead of going through dyndns.org as before.
