need to understand BT connection protocols
Posted: Thu Mar 07, 2013 1:16 am
Hello
Let say i chose Port 54128 in transmission-daemon.
I have deactivated PEX and DHT. I also have "port-forwarding-enabled": false", which is I guess the same as deactivated "NAT-PMP/UPnP" option within the GTK application.
Also I choose "utp-enabled": true, which is I guess the same as activated "µTP support" option within the GTK application.
Do I need to open both UDP & TCP 54128 incoming ports in my netfilter firewall or only TCP ?
If I drop UDP, I see a lot of connections rejected on incoming UDP 54128. But if I open it, I never see UDP connection on that port using netstat ???
Also, I am suprised to see transmission connections on ports other than the specified one, using netstat -taupen ?
at the time of this netstat snaphot I was only seeding, not downloading. I understand the 3 latest ones but not the 4 first ones...........;
I also have connections on TCP 9091 but this is clear for me as related to the web client (limited to my internal network).
In terms of outgoing ports, what kind do I need to open ? Only 80 for tracker localization ? Others ?
Thanks,
