SSH? Or, if all the machines are behind your firewall, telnet?

How would you do it without python?

Welcome!

Just login to the desired server and run the command. If you can't reach it I doubt that you could manage the router ;) If I am net admin I won't allow such a thing.

You'll have to port forwarding the data stream:

PC_IP:3000  <-> 3000:SERVER_1_IP:3001 <-> 3001:SERVER_2_IP:3000 <-> 3000:ROUTER_IP
With port forwarding every data that arrives at port 3000 (just for example) will be forward to the port 3001 (example)

Thanks for your reply,
On servers I do it using SSH and on Routers few with SSH and few with Telnet

Search for port forwarding for the OS of both servers and for the specific router model.
It is not a big deal. If the servers are running Linux, you can do it using "iptables".

Let us know about your progress.

Ok, then do it with python using ssh or telnet. The approach using python won't be any different from what you already do, you'll just be automating it.
