OpenSSH : SSH Port Forwarding2021/08/17

	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

debian@dlp:~$

ssh -L 10.0.0.30:8081:10.0.0.51:80 debian@node01.srv.world

debian@node01.srv.world's password:

# password of the user

debian@node01:~$

# confirm state

debian@dlp:~$

ssh dlp.srv.world "ss -napt | grep 8081"

debian@dlp.srv.world's password:
LISTEN 0      128        10.0.0.30:8081       0.0.0.0:*     users:(("ssh",pid=5245,fd=4))

# listen on 8081

# keep the 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.
