a few days ago i migrated from npm to pangolin (v1.9.4) and im experiencing heavy packet loss when connected to the teamspeak instance in my homelab

connection info when connected via tunnel

now to make sure teamspeak itself is not the cause here, i setup a seperate firewall rule and dns record to connect to the teamspeak without routing and tunneling, which resolves the packet loss entirely.

steps to reproduce

1. docker teamspeak instance on an external site connected via newt (v1.4.4)

services:
  teamspeak:
    container_name: teamspeak
    image: teamspeak
    restart: always
    ports:
      - 9987:9987/udp
      - 10011:10011
      - 30033:30033
    environment:
      TS3SERVER_DB_PLUGIN: ts3db_mariadb
      TS3SERVER_DB_SQLCREATEPATH: create_mariadb
      TS3SERVER_DB_HOST: ***
      TS3SERVER_DB_USER: ***
      TS3SERVER_DB_PASSWORD: ***
      TS3SERVER_DB_NAME: ***
      TS3SERVER_DB_WAITUNTILREADY: 30
      TS3SERVER_LICENSE: accept

2.

create TCP/UDP resource for port 9987/udp pointing to the external teamspeak instance, in my case

site: homelab, ip/hostname: 192.168.0.4, port: 9987

update traefik_config.yml entrypoints

udp-9987: # teamspeak
    address: ":9987/udp"

update gerbils ports in docker-compose.yaml

- 9987:9987/udp # teamspeak

open VPS ports (hetzner in my case)

3. connect to teamspeak server via the TeamSpeak client

any help appreciated, im fine with my current bandaid solution, but for completions sake and learning i would still like to know what could be causing this to happen
