ssh Туннель -L -R Где какой порт: локальный и удаленный - Туннелирование
Primary tabs
Собственно:
- Если у вас флаг -L:
ssh -L
то первым указываются локальный адрес (если нужно) локальный порт, как в этой заметке про туннель
- Если флаг -R:
ssh -R
то первыми идет адрес (если требуется) и порт удаленного узал

Ниже цитаты с описаниями:
-L [bind_address:]port:host:hostport -L [bind_address:]port:remote_socket -L local_socket:host:hostport -L local_socket:remote_socket Specifies that connections to the given TCP port or Unix socket on the local (client) host are to be forwarded to the given host and port, or Unix socket, on the remote side. This works by allocating a socket to listen to either a TCP port on the local side, optionally bound to the specified bind_address, or to a Unix socket. Whenever a connection is made to the local port or socket, the connection is for‐ warded over the secure channel, and a connection is made to either host port hostport, or the Unix socket remote_socket, from the remote machine. ............ -R [bind_address:]port:host:hostport -R [bind_address:]port:local_socket -R remote_socket:host:hostport -R remote_socket:local_socket -R [bind_address:]port Specifies that connections to the given TCP port or Unix socket on the remote (server) host are to be forwarded to the local side. This works by allocating a socket to listen to either a TCP port or to a Unix socket on the remote side. Whenever a connection is made to this port or Unix socket, the connec‐ tion is forwarded over the secure channel, and a connection is made from the local machine to either an explicit desti‐ nation specified by host port hostport, or local_socket, or, if no explicit destination was specified, ssh will act as a SOCKS 4/5 proxy and forward connections to the destinations requested by the remote SOCKS client. .............
