Example:

1. 正向隧道 / remote port 導入至 local port (訪問 local:local-port 等於訪問 remote:remote-port)
   ssh -o ServerAliveInterval=60 -N -L {local}:{local-port}:{remote}:{remote-port} {user}@{remote}

2. 反向隧道 / local port 導出至 remote port (訪問 remote:remote-port 等於訪問 local:local-port)
   ssh -o ServerAliveInterval=60 -N -R {remote}:{remote-port}:{local}:{local-port} {user}@{remote}
