ANSWERED can't seed torrents when ufw is enabled

[Baren Rauth 0]

so i am using ufw as killswitch for my openvpn connection using this tutorial https://gist.github.com/Necklaces/18b68e80bf929ef99312b2d90d0cded2
i can download torrents with no problem, but when it comes to seeding i have to disable ufw to make it work . 
i have tried different torrent clients, whitelisted the torrent clients with gufw but no success so far .

ufw is an interface to netfilter, which accepts socket definitions – protocols, IP addresses and ports. It does not support applications like /usr/bin/firefox. The "application support" ufw talks about refers to profile files describing protocol/port/address definitions organized in a group, so you can use ufw allow <app name> as a shorthand for multiple allows.

Are you sure your torrent clients are bound to the interface tun0?

update: fixed the issue with port forwarding enabled . i think port forwarding is mandatory to seed a file with a torrent client .

Hello!

Yes, it's mandatory and it is a direct consequence of the inner essence of the BitTorrent protocol. If no peer were reachable BitTorrent would not work at all, just like any other service on the Internet would cease to work if no node could be reached.

Kind regards

In a way, this is a rather funny "fix". I was writing under the impression that having a forwarded port is par for the course… but I guess I should ask the equivalent of Are you sure it's plugged in? from time to time, to really verify things we kind of take for granted.

Well, I'm glad it's fixed. Enjoy!
