I want to be able to ssh into work-pc that is behind a restrictive firewall from home-pc.
Work-pc openssh version
OpenSSH_7.2p2 Ubuntu-4ubuntu2.1, OpenSSL 1.0.2g 1 Mar 2016
I use this command on work-pc: ssh -p443 -fNTR 0.0.0.0:6333:localhost:443 [email protected]
I use this command on home-pc:
ssh -v -p 6333 localhost
output from home-pc:
OpenSSH_7.3p1, OpenSSL 1.0.2j 26 Sep 2016
