Remote Desktop port issue through multiple hops internally.

Last Modified: 2013-11-21
Hardware involved
One DSL Modem/Wireless Gateway (Actiontec GT701WG)
One Router w/Wan IP (Siemens Speedstream 2602)
One Laptop connected wirelessly to the .0.1 gateway
One Desktop connected via ethernet to the 254.254 gateway.

forwards I have set up are is set up to pass 3389 to is set up to pass 3389 to

What I CAN do: Remote from my laptop to the desktop by using the WAN IP of the router (.0.2) AND remote from my desktop to my laptop using the direct ip (.0.5)

Using the logic that i CAN connect to i configured the modem to forward port 3389 to 192.168.02, since it's configured to pass that on down to 254.38 anyway

yet, it doesn't work, it doesn't work if i set up a forward directly to the IP of the computer either, and cannot attempt to establish a direct connection to the 254.38 ip..

NAT is enabled on both devices, and cannot be disabled on the router at all, there is simply no option for it, not sure if that has anything to do with it but i'm not sure how it would, as internally, the connections work fine, it's just running in to a wall somewhere and i'm not sure where.
