Hi, I'm a little bit confused about port forwarding inside a LAN. I have a linux box that I call a home server. This server is doing for some basic tasks such as samba server, torrent, ssh server, media server, and so on. My confusion is that in the router, I have to forward a port for ssh to connect to the server from my laptop. However, the laptop can connect to other services without any port open at the router. So do we need to open ports inside LAN? Why SSH requires its port open but the others don't? Thanks!
