You would set it based on the range your ISP tends to assign you, and remove 0.0.0.0 for the ssh port.

Unfortunately. I have seen some ISPs DHCP servers assign IPs with no particular subnet(s). Could be a case here as well.

That’d be frustrating, not just for this. I’d probably be looking into a solution like Tailscale to tunnel out. Or just develop a gnarled security rule list full of rich history. :)
