That was going to be my guess. For example Transmission has a setting for UPnP/NAT-PMP port forwarding. Is there anything similar in rtorrent? For that to work, the corresponding setting needs to be turned on in the router as well, or the UPnP requests _should_ be ignored/rejected by it. If it works on a different computer on the same network, that seems unlikely to be the problem. >>>> ipv6 is disabled >>> >>> Then it cannot work, because peers cannot reach you with IPv6. >> >> How-to enable ipv6? > > You need to go to the routers settings, I don't have openwrt to test. IPv6 should not be necessary for normal Bittorrent usage. It's not a bad thing to have, and it might help in some situations, but just "enabling" IPv6 is unlikely to help, especially if Jason's ISP doesn't provide globally routable IPv6. Bittorrent behind NAT on IPv4 is common enough to be considered widely used. -- Michael Kjörling 🔗 https://michael.kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”
