How to ssh,putty,vnc,nx through networks by port forwarding

[roland]

Hello,
I have an installation FED9 192.168.9.0/24 in site-1 and another EL5  
192.168.0.0/24 in site-2. Both networks are connected via the internet,  
because they are in different cities. I have no possibility to enter in  
network-2 because it is a special service of French Telecom. So I enter  
via a router in network-1,over internet, then connect to the server FED9  
192.168.9.254 by port forwarding and then I do ssh,putty,vnc further to  
network-2 passing the router 192.168.9.97 which give me the routing to  
network-2

I tried to do port forwarding to network-2 directly but this does not  
work. I can ping the server on network-2 from the router, that gives me  
the entrance via internet to network-1 (it is a netopia)

Shortly:
Internet -> router-1 netopia on network-1 -> portforwarding to server on  
Network-1(192.168.9.0/24) -> manually connect to network-2  
(192.168.0.0/24) over router-2 {router french telecom -> internet ->  
server on network-2)

I would like to:
internet -> router-1 - port forwarding - server on network-2

I hope this is clear and understandable.

Any help would be very much appreciated
