Port Forwarding Help

[Marc Perkel]

I hope this is the right list. I need help.

This is something that should be simple for all you smart people out there.

I have 2 email servers that I want to communicate with each other. Both 
have port 25 open. But - they only bind on port 25 to specific IP 
addresses. So - what I want to do is this:

I want to do an ssh tunnel to the other server. SSH doesn't do that 
gracefully - but I did get it to work listening on port 26 and piping to 
port 25.

ssh -f -N -C -L 26:localhost:25 destination

So - here's what I want to do. I want to port forward 1 ip address on 
port 25 on the local machine to port 26 so for example :

127.0.0.2 on port 25 to 127.0.0.2 on port 26 so if I connect to 
127.0.0.2 on port 25 it goes over the tunnel to the other server.

It can be that hard - but I'm just not very smart.

Thanks in advance for your help.
