[Solved] IPv6-specific firewall rule

I created a firewall rule for my ssh server: "ufw allow xxxx/tcp", where xxxx is the port number of my ssh server. It worked just fine for IPv4 and IPv6, but it allowed access from anywhere.

I wanted access to be allowed only within my LAN. So, "ufw allow from 192.168.1.0/24 proto tcp to any port xxxx" worked just fine for IPv4, but it does not handle IPv6.

How would I do an analogous command for IPv6? Would it be something like "ufw allow from aaaa:bbbb:cccc:dddd::/64 proto tcp to any port xxxx"? Or something else entirely?

Re: IPv6-specific firewall rule

That is correct*, assuming you're working with a /64, and not something larger and want to include it (/48 from HE.net, etc). You are most likely working with a /64, though.

* I don't know anything about ufw syntax, but that's how you'd do it any firewall I'm familiar with.
