Post subject:  bad ports with bitTornado

I use bitTornado under Linux - Ubuntu.
My netgear firewall is configured well. My ports 6881 until 6889 are opened. bitTornado has 6881 at 6889 ports range. But when I look at with the command :
netstat -n, this one the results :

0 127.0.0.1:46657 127.0.0.1:631 ESTABLISHED
tcp 0 0 127.0.0.1:631 127.0.0.1:46657 ESTABLISHED
tcp 0 0 192.168.0.3:6881 84.178.233.159:50573 ESTABLISHED
tcp 0 0 192.168.0.3:49312 82.170.227.187:6881 ESTABLISHED

tcp 0 0 192.168.0.3:6881 82.213.155.103:1428 ESTABLISHED
tcp 0 0 192.168.0.3:6881 62.61.148.252:37845 ESTABLISHED
tcp 0 0 192.168.0.3:35424 200.106.137.108:6881 ESTABLISHED
tcp 0 0 127.0.0.1:53384 127.0.0.1:32770 ESTABLISHED
tcp 0 0 192.168.0.3:6881 87.3.49.88:1928 ESTABLISHED
tcp 0 0 192.168.0.3:36181 83.52.116.20:6881 ESTABLISHED

Hense I think that bitTornado uses any ports others than 6881 at 6889, such as 49312 etc. This may be why my download may be slow.
I dont know if it is nomal, but I would rather to say it.

Actually it is quite normal. BitTornado can use almost any outgoing ip port -- it will just only accept INCOMING connections automatically only on the narrow range of ip ports that you allow.

Notice that these ip connections I cut out of your list ALL connect to an ip on port 6881. Your computer is connecting to them on the ip port they use for incoming BitTorrent traffic.

Also notice that these connections:

tcp 0 0 192.168.0.3:6881 84.178.233.159:50573 ESTABLISHED
tcp 0 0 192.168.0.3:6881 71.121.141.97:2211 ESTABLISHED

...are connecting to your ip port 6881 but they're not using ip port 6881-6899. That's because the outgoing port BitTornado (or even web browsers for that matter) use is random and/or decided by your operating system.
