Ktorrent not working

English Network/Internet
1

hi,
I have made a new install on Leap 16 with all up to date packages.
I configured my router to make ip forward to all ports for all specified tcp and udp port realted to not only KTorrent but other torrent clients.
hen I opened on firewall-config the related services. I added a service named Ktorrent and therefore I expected the ports would be binded to KTorrent
But nothing works. I mean I can download magnet links and they show up on KTorrent but the traffic is zero all the time.
KTorrent needs the following ports:
6881 tcp
8881 udp
7881 udp

They are enabled on firewall-config as the service and also at the Public Zone level.

so the ports are supposed to be opened at the router and in the firewall
I used wireshark and there are some registered calls on port 7881
Nothing on 6881, and that is the main torrent port.
When I make something like:

netstat -lunpt|grep ktorrent
tcp6       0      0 :::6881                 :::*                    LISTEN      15352/ktorrent      
udp        0      0 0.0.0.0:7881            0.0.0.0:*                           15352/ktorrent      
udp        0      0 0.0.0.0:8881            0.0.0.0:*                           15352/ktorrent      
udp6       0      0 :::7881                 :::*                                15352/ktorrent      
udp6       0      0 :::8881                 :::*                                15352/ktorrent

I see port 6881 Only listening and binded to KTorrent on port 6681 Only in IPV6 !?
This is strange and I think this can be the cause I can not download anything …
Is this the problem with KTorrent?

I want ot make a correction, the listing above shows binding on both ipv4 and ipv6.
I do not know if the router uses ipv6 .
But it sure does use ipv4.
And on wireshark there is nothing on ports 6881/tcp or 8881/udp
but there is some traffic on port 7881/udp
port 7881 is the DHT port
I forgot to mention that I use a Bridge on NetworkManager since I need some VirtualBox and other Hosts therefore the bridge is necessary.
This should not have an impact on KTorrent but if anyone has a different experience let me know.

I found out the problem and it was a simple issues with defective torrent files. I also had to reboot the router so it is not related with anything of the firewall that does have the ports open and the router has the correct port forward.
