OpenSSH : SSH Port Forwarding2022/04/25

 
It's possible to forward a port to another port with SSH port forwarding.
[1] For example, set SSH Port Forwarding that requests to port [8081] on [dlp.srv.world (10.0.0.30)] are forwarded to port [80] on [node01.srv.world (10.0.0.51)].
# SSH login from source host to target host

ubuntu@dlp:~$
ssh -L 10.0.0.30:8081:10.0.0.51:80 ubuntu@node01.srv.world

ubuntu@node01.srv.world's password:  
# password of the user

ubuntu@node01:~$
# confirm

ubuntu@node01:~$
ssh dlp.srv.world "ss -napt | grep 8081"

ubuntu@dlp.srv.world's password:
LISTEN 0      128        10.0.0.30:8081       0.0.0.0:*     users:(("ssh",pid=1055,fd=4))

# listen on 8081
# keep this login session
[2] Verify to access to a port on source Host you set from any client Host, then target port on target Host replies.
