Firewall slowing down and dropping torrent connections

[PF4PFS]

Hi guys

I am having problems when I use torrents;
Below is the rule that enables outside clients to reach the workstation that runs Torrents

I am seeing a lot of connection initiated from outside to port 54321 (torrent client) that are being dropped
At the same time after a while I firewall slows down making the browsing very slow and other connection initiated from outside ( like, RDP or http)  impossible to establish.
I believe that this is probably related to some FW limits that have to be adjusted but I am not sure what exactly is being saturated

Does anybody know what I have to do to fix this?

thank you

For torrents, you likely want to also open UDP port 54321.

Are you saturating your connection's bitrate? Traffic-shaping can help.

By default, pfSense should be able to handle a hundred thousand states ("connections").
