Torrent client instantly kills connection

[maskedval]

Jio Fiber seems to have some aggressive traffic control for torrents. I see about 50% packet loss as soon as torrent client is opened, I'm just using 10KBps to test, also limited connections to 10-20 to test. Using mtr and wireshark to look at packet loss%. I tried different clients, so I know it's not specific client. If I leave QOS on router, I can't open single website. I saw using QOS option on UDP connections (assuming this is packets per second). Packet loss is contained from router to Jio gateway. My connection still dies pretty quick. I'm currently just rate limiting udp packets/s with iptables, which worls well for me. Wondering, if anyone else has faced issue, and have you managed to figure out anything?

Router: JCOW414
Router Firmware: SRCMTF1_JCOW414_R2.35

Yes, Jio seems to have limitations on the amount of TCP/UDP connection each customer (as a gateway) is allowed to make. Regardless, how are you testing this issue?

I see, makes sense. I basically open torrent client on my PC and run mtr. Mtr combines ping and traceroute to show packet loss percentage. I tried reducing connections to 5-10, but torrent clients usually will have peer connections, DHT etc and not everything is configurable. Here are my rules for iptables which works for me, if anyone's interested. I've disabled DOS protection on router, that is way too aggressive IMO.

iptables -A OUTPUT -o enp2s0 -p udp -m limit --limit 16/sec --limit-burst 20 -j ACCEPT

ip6tables -A OUTPUT -o enp2s0 -p udp -m limit --limit 16/sec --limit-burst 20 -j ACCEPT
