I’m going to be away from home for a few weeks and would like to access my computer (LMDE) while I’m away. Remote desktop connection would be ideal, just file transfer would be acceptable.
Is a VPN necessary, or can port forwarding be good enough for a one time use?
What software/networking recommendations do you have?
Opening ports is also trivial. You don’t generally need a dedicated IP if you keep a connection running but YMMV. And you don’t need a domain - just remember the IP. This is only for a few weeks.
If you’re behind cgnat oppening ports on your router won’t do you any good. You have to call your isp and ask them for a dedicated public ip, usually for a price if they offer one at all. If that ip is static you can remember it, if not, you need ddns. If you’re one of the lucky few not behind cgnat then yeah, your setup will be the simplest possible, but if you are, like the majority of people these days, it’s one of the most complicated.
Well yeah, duh.
