How do you like to transfer large files between friends across the internet? (lemmy.world)

On occasion I find myself needing to send a file at least a few gigabytes in size to a friend across our slow ISPs but haven't found a satisfying solution. I usually end up creating a private torrent with the announce address of my own IP. Even though it's slow - it basically never reaches my max upload speed for some reason, it is at least resilient if there are ever any network glitches.

Does anyone else face this same challenge?

EDIT: Thank you for the awesome suggestions! I have some homework to do on these

> is there such a problem? honest question. But I think that might be a different issue

Yes, that is a problem. We're still in a world where you need to manually enable port forwarding in order to get better seeding for bittorrent clients, and if you have CGNAT you're SOL (short of using a VPN or something to bounce through an external host).

It's likely because torrent software is older (& in crappier languages), and came about before CGNAT was a thing.

I don't understand, sorry. they were saying that something doesn't work as expected IPv6. but CGNAT is not used for IPv6, is it? and you don't really forward ports either, maybe you allow them through in the routercs firewall but notnsure because I don't have v6

We're still in a world where you need to manually enable port forwarding

well, you don't need to, often you can also enable the upnp function in the router so that any software can open all the ports it wants, which is a terrible idea security-wise
