Hey, I'm using pfsense since january 2024. Everything works perfectly fine. I get 1000mbps down and 300mbps down everywhere - besides telegram app. Upload speeds in telegram are horrbile. 10mb photo can be uploading for 30 minutes.

My first thought was that pfblocker is blocking telegram, so i removed it and all of the rules of pfblocker. It didnt help. So i reinstalled my dell optiplex with fresh pfsense installation (without any plugins) - and the results are the same. Telegram takes ages to upload something.

Then I removed my pfsense box from my network and connected my ISP router - telegram works without any issues. Uploads speeds are perfectly fine.

Once again I connected my pfsense box, connected on my pc to VPN (ProtonVPN) - and upload speeds on telegram are perfectly fine.

So VPN pfsense telegram is working normal.

But pfsense telegram - give me slow upload speeds.

Can anyone help me with the solution to this problem?
