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

    tailscale and zerotier are wireguard, but with a public server that helps with NAT. Syncthing uses a public server for that too.

    wireguard was specifically made to be as simple and minimalistic as possible.

    Zerotier wasn’t always Tailscale was it?

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

    You need to be connectable to download from all the peers, likewise non connectable users can’t download from you, and how do you become connectable? By opening your ports, something that might seem archaic from somebody who has totally embraced IPv6.

    maybe they just don’t see working on it profitable enough

    Yeah maybe.

    Just to clarify, I have several workarounds for the 3 issues that have involved spending more money or not to get rid of CGNAT.

    • For the 1st one… Well I already mentioned it, I am a ZT and Tailscale user, I did try Wireguard from a VPS once though, but I didn’t like that I was entirely dependant of my upload speed, maybe I had my Iptables wrongly configured but I usually got faster speeds just using ZT or Tailscale (I didn’t need to relay in the US VPS server).

    • For Torrenting… I actually haven’t found a solution to use IPv6… I did use a container client to use my VPS at that time though, it being Digital Ocean and thus getting a DMCA letter for downloading TWD me being a LATAM user was… A kinda funny experience, with that said I stopped that project immediately, it was fun to give back to the community with my 24/7 NAS always seeding though.

    • For the last point… Well, I do use ZT and Tailscale to access the server myself, but when I want to expose it, I usually do it with a reverse proxy pointing out to my IPv6 address, and more recently using a Tailscale funnel, I haven’t tried it thoroughly, but at least it seems to connect without using Plex’s relays.

    As you can see, one needs to be well prepared with workarounds to deal with CGNAT.

      it is not tailscale. but also it seems I was wrong and its not wireguard either

      I know what opening ports is, I only have v4. But I thought you have difficulties with bittorrent over v6. or is it that you still need to open ports for v6, in the firewall or something?

        Yeah, I totally meant Wireguard there, my bad.

        I don’t have difficulties to download, I have difficulties to seed because I am CGNATED and it seems Qbittorrent or any Torrent client really can’t use IPv6 to be more connectable thus seed more.

        I want to seed more without having to pay for it or do convoluted workarounds.
