Which ports need to be allowed through firewall to seed torrent using transmission-cli on headless server?
Matthew Martinez
Self-hosting my own tracker using bittorrent-tracker.
Opened UDP port 6969 on tracker and seed servers.
What else needs to be allowed?

For both the tracker as well as the torrent client the answer is the same:
The ports you configured.
Trackers traditionally listen on TCP port 6969. They could be listening on other ports (both TCP and UDP), too. It depends on the setup.
BitTorrent technically has well-known ports (TCP 6881-6889). The DHT protocol may use different UDP ports. The uTP protocol may use different UDP ports. In practice, it again depends on the configuration.
If you are behind a NAT gateway of any kind, you also need port forwarding.
