If I create a new torrent, does CGNAT (carrier-grade network address translation) prevent me from being an initial seeder of that torrent? I’ve made test torrents before and noticed that none of them seemed to be downloadable. Seeding the test torrents on a VPS of mine with a public IP has surprisingly worked before.

I can download and upload in my torrent client just fine, so I know my ISP isn’t (intentionally) blocking and firewalling torrents.
