Hi, i hope this is not to stupid.

This is the scenario:


pc1 machine work behind router
pc2 ssh server somewere
pc3 machine home direct access to internet


I don't have access to the roauter at work, so i was thinking to open a ssh tunnel with putty to pc2 (midle server) this way as long as the tunnel is opened i don't have to worry about the router.

Then i make a socks from my ssh server (pc2) ssh -g -D 9000 admin@localhost, now in firefox at pc3 im using pc2 as socks.

The question is how can i setup pc2 (ssh server) to send all traffic received by socks on port 9000 to the tunnel i opened from pc1 to pc2?

this looks like some kind of port forwarding is needed?

• a thing for iptables?
• /proc/sys/net/ipv4/ip_forward

Well i have found the solution, is like that if somebody is interested.

from pc1 putty
putty -c -R 5600:localhost:8080 -l user@domain -pw pass

from pc2 server
ssh -4 -g -v -L 5000:localhost:5600 user@domain -N

Listen to port 5000 (-g) from any host then forwards to 5600 to pc1 and putty is forwarding the port to port 8080. Opening the putty connection from pc1 to pc2 will bypass the router restriction.
