Traffic Shaping

Hi there.

I've got a strange problem, but first my network.

As you see, my m0n0wall connects to an another router, because the set top box requires the isp's own device.

The story:
Everything worked fine, until some days ago the isp's device had broken down. It had been changed to a new one, but the torrents not working fine since then, everything else is working fine including ftp server, emule, etc. You can say, the isp is blocking the torrents, but i think they not. The isp's device have some other utp ports, and if I forward the ports there, putting there a pc directly, the forward works. I've switched the ports of the m0n0wall and that pc on the speedtouch, but it still didn't worked.
When i changed the port of the forward to an number under 10.000, it worked. But some tracker blacklisted the ports under ~50.000, so this solution is only temporary. When i changed back the port to the previous, it failed the tests again.

I'm not sure where is the problem. At this moment, i think it's maybe a m0n0wall bug (but I've tried 1.233 and the latest 1.3b), or the new speedtouch forwards the port over 50.000 in a non-regular way, so m0n0wall can't handle it (only the wins?)

When today I changed the speedtouch to single adsl modem, the portforward for the torrent worked correctly (but there is no iptv stream this way).

Almost forgot to mention, i've tried sysloging the firewall rule letting through the torrent connection, but there wasn't any entry in the log, like the data couldn't reach m0n0wall.

What do you think, why only windows systems works properly with the speedtouch's port forward?
