SSH Local Port Forwarding

Forwarding one port on the client system to exactly one port accessible from the SSH pivot server. It's still confusing no matter how many times I read it.

# Below sets up local port 8123 forwarded thru victim to reach port 80 on target.local
ssh -L 8123:target.local:80 [email protected]
curl localhost:8123
attacker:8123 -> ->
# Below forwards a port on the victim localhost to be accessible (i.e. MySQL for localhost only)
ssh -L 3306:localhost:3306 [email protected]
mysql -u root -p

SSH Dynamic Port Forwarding

SOCKS Proxy used to forward several ports. Can use proxychains to help non-proxy aware programs to reach the intended destination. Do not try to port scan through a SOCKS proxy, it is VERY SLOW!!

ssh -D 9123 [email protected]

SSH Remote Port Forwarding

A port on the pivot system is forwarded to a local port, not commonly used.

ssh -R :8123:localhost:80
ssh -R :8000:www.google.com:80

Meterpreter/MSF Forwarding

Can use built in mechanisms in meterpreter/msf to port forward or route easily

# Cmd below will create a local port on to reach target:80
meterpreter > portfwd add -l 4321 -r target -p 80
