Yesterday I changed my ISP to one that allows port forwarding. Today the port forwarding has been enabled by the company and I set it up on the router.

After enabling it, my download and upload speed dropped from peaks of 50 MiB/s and valleys of 4-6 MiB/s to a very stable 2 MiB/s. Nothing else has changed in my qBittorrent configuration. If I close the ports again, the speed goes back to normal. I checked if the ports were open on various websites and all of them show that they are forwarded.

I was looking forward to be able to port forward and connect with every possible peer for years, and today has been a big disappointment in that regard!

Has anyone else seen something like this and if so, can you point me to the right direction to fix the problem?

What about other traffic?

Other traffic is fine. That's what was screwing with me, but after reading some people say they might be fucking with my connection due to seeing it is a bittorrent connection, everything makes more sense.

Are you running on port 6881? Pick a random one above 10000 and see if it changes.
