(But it is better if you allow the port in your firewall frontend (ufw, gufw, firestarter, e.g.) for permanent solution.) If you want to make it permanent you can put this command in a startup script. This is only a temporary solution, after reboot this firewall setting is lost. Sudo iptables -I INPUT -p tcp -dport PORT_NUMBER -j ACCEPT
#TRANSMISSION FOR MAC PORT CLOSED HOW TO#
If you use a firewall but you don't know how to allow that port, use the following command where PORT_NUMBER is the port used for incoming connections in Transmission: If you activated some kind of firewall then you have to change those settings to allow incoming connections on that port.

If you use Ubuntu with the default settings and didn't activate a firewall then the linux firewall won't block any port. That port can be blocked either by your router or by your firewall. To open that port: First find out the number of the port in Transmission under Edit->Preferences->Network->Port used for incoming connections. Actually non of the peers would be able to do anything as everyone is passive, you will have to wait until an active peer comes in.) (If that rare case happens that all the peers are in passive mode, then you won't be able to download/upload anything.
#TRANSMISSION FOR MAC PORT CLOSED TORRENT#
If the torrent has few peers then it is likely that with active mode you would get much better speed. But if the torrent is frequent and there are lot of peers your client will likely be able to find enough active peers to max out your connection. That means that you may get less peers and because of that worse speed. So if your port is closed that only means you can't connect to other peers with closed ports. A client in active mode can connect to both active and passive clients. So it works like this: A client in passive mode can connect to a client which is in active mode, but not to a client which is in passive mode. In torrent terminology this is called active mode. If your port would be open then you would be able to accept connections too. In torrent terminology they say that you are in passive mode. If the port is closed that only means you can't accept incoming connections, but you can still connect to peers who accept connections. The short answer to the question: YES, you can seed with closed port too. This answer on AskUbuntu sums it up nicely: From what I have found online its still possible to seed when the port is closed (known as passive mode) however when downloading in passive mode will find less peers so may experience a slower than possible speed, I think this is what's happening to me.
