For example, I prefer to use a VPN instead of port forwarding. And I use SSH for anything I used to use an FTP for.

  • IP whitelisting

    How do you do that? I understand how blocklisting would work but how does whitelisting work in practice? How can you know in advance from which IPs you will connect to your home network in the future? That just seems like a recipe for getting stranded in some hotel without a way into your network.

    • Blacklist everything then whitelist the IPs you know you’ll be connecting from (work, cell phone, etc). I don’t connect from random places usually. If I need to then I use cellular. You might be better off with a VPN if you need to connect from random places.

        I see, thanks!
        Is there any concern with whitelisting a cellular CGNAT’s public IP? Presumably that would potentially whitelist thousands or tens of thousands of other mobile devices at once, wouldn’t it?

          It depends on how much you decide to whitelist. In my case I whitelist my cellular carrier’s IP block. Which does expose those services a little more broadly but I’m willing to risk it.
