Set up a revserse tunnel to bypass NAT to a remote machine
Useful to log into a remote machine (remote) with account (remoteaccount) that is behind a NAT firewall.
Create an account on a machine on the Internet (middle.some.place) which is available from both sides and set a password:
useradd -s /bin/bash middleuser passwd middleuser
From remote machine
ssh -R 10002:localhost:22 middleuser@middle.some.place
The remote user will log into the middle machine. The terminal must stay open for the duration of the connection.
if you're logged into the middle.some.place.... you can then do:
ssh remoteaccount@localhost -P 10002
and that should be it
