SSH Allowing remote hosts to connect to local forwarded ports

Sometimes some ISP dont allow user to use port 22 to ssh other server then user could not connect his desired server.
To solve this problem in server which user wants to connect, another port should be forwarded to 22 port. Then user can connect to that port.

In server side, someone should forward that port. Thats the problem... :(

server side: ssh -gL 8022:localhost:22 localhost

& user should use -p switch to connect that server.

user side: ssh -p 8022 [email protected]_name
