Is it possible to use UFW to limit ssh access to a server by an external host by its MAC address? I now have a permanent IPv4 address for my home IP router and would like to access my home server from my laptop when away from home, but allow no other external access. Is that possible?
This is in addition to the other answers. If you have a server which is publicly available, you can only "restrict" by IP, rate limiting, port nocking and having your server properly secured and isolated. -- John Doe
