Tunneling X11 through intermediate host

server1 intermediate host

server2 destination

2200 is an example port on localhost, this could be assigned other ports as well.

OpenSSH

$ ssh -L2200:server2:22 server1
$ ssh -p2200 -X localhost

PuTTY

1. Set up the tunnel and open a connection to the intermediate server:

Once the connection is established, keep that window open to maintain the port forwarding.

2. Then SSH to localhost:2200 with X11 forwarding enabled.
