I decided to use a time tested approach of trial and error. This is what allowed access to proxy2: ssh -t -t -D proxy1 -R proxy2:127.0.0.1:proxy2 -p remoteSSH [email protected] In Firefox, I can now enter: https://127.0.0.1:proxy2 which will send the connection through the tunnel (proxy1) to the local proxy (proxy2) essentially becoming a local-remote-local tunnel to a specific port.
