Becoming not connectable after a while.

My ports are all open. Every tracker says I'm connectable. When I make connection test in uTorrent I'm connectable.

After few hours (sometimes less, sometimes more) the trackers begin to see me as not connectable. When I make the connection check in uTorrent it says I'm not connectable. Right after I check again, the same port. It says I'm connectable. Than all trackers see me as connectable again. After some time I become not connectable. The trackers again say I'm not connectable. The connection test in uTorrent report the port to be closed. I check the port for a second time and uTorrent says its open. Than the trackers again report me as connectable. For some hrs ....till I become not connectable again.

I dont know if that matters, It seems that I am able to seed. But it's really annoying. And kinda looks ugly to see on all trackers in your profile not connectable.

i am taking a double take here, but it might be your ISP playing around with you,

if not, then i have nooooooo idea
