Remote Desktop with 2 networks and RRAS

[Zen11]

Here is my setup :

Internet
xxx.xxx.xxx.xxx (external IP)
RRAS (W2K Routing and Remote Access Service)
192.168.7.254 (intenal IP)

192.168.7.234 (external IP)
Linksys Router WRT54G
192.168.1.1 (internal IP)

Computer IP 192.168.1.10

On RRAS(NAT), port 3389 is forwarded to 192.168.7.234
On Linksys Router port 3389 is forwarded to 192.168.1.10

Try to connect from outside (Internet) to xxx.xxx.xxx.xxx NO good (error : The client could not connect to the remote computer.)

Try to connect from a computer on first network (192.168.7.xxx) to 192.168.7.234 GOOD!

Change on RRAS to forward port to 192.168.7.xxx
Try to connect from outside (internet) to xxx.xxx.xxx.xxx Good! (it connects to the pc on the first network)

I've tried cutting down this problem into parts and each time it worked, so i am really lost.... Anyone have any ideas? It does not work only if i put everything together but i think my settings are ok...
