Hey there,

My Firewall is the ufw firewall with following Settings:

When i start the TCP test it works:

turnutils_uclient -W SECRET turn.obco.pro -T

0: : Total connect time is 1

0: : 2 connections are completed

0: : start_mclient: msz=2, tot_send_msgs=0, tot_recv_msgs=0, tot_send_bytes ~ 0, tot_recv_bytes ~ 0

1: : start_mclient: msz=2, tot_send_msgs=0, tot_recv_msgs=0, tot_send_bytes ~ 0, tot_recv_bytes ~ 0

2: : start_mclient: msz=2, tot_send_msgs=5, tot_recv_msgs=5, tot_send_bytes ~ 500, tot_recv_bytes ~ 500

3: : start_mclient: msz=2, tot_send_msgs=5, tot_recv_msgs=5, tot_send_bytes ~ 500, tot_recv_bytes ~ 500

4: : start_mclient: msz=2, tot_send_msgs=5, tot_recv_msgs=5, tot_send_bytes ~ 500, tot_recv_bytes ~ 500

5: : start_mclient: msz=2, tot_send_msgs=5, tot_recv_msgs=5, tot_send_bytes ~ 500, tot_recv_bytes ~ 500

6: : start_mclient: tot_send_msgs=10, tot_recv_msgs=10

6: : start_mclient: tot_send_bytes ~ 1000, tot_recv_bytes ~ 1000

6: : Total transmit time is 6

6: : Total lost packets 0 (0.000000%), total send dropped 0 (0.000000%)

6: : Average round trip delay 0.000000 ms; min = 0 ms, max = 0 ms

6: : Average jitter 0.300000 ms; min = 0 ms, max = 1 ms

6: : Average jitter 0.300000 ms; min = 0 ms, max = 1 ms

But with UDP it fails:

turnutils_uclient -W SECRET turn.obco.pro -v

This is my docker-compose setup:

coturn:

image: coturn/coturn:latest

container_name: coturn

restart: always

volumes:

- /docker/Matrix-Synapse/Data/Coturn:/etc/coturn

ports:

- 3478:3478

- 3478:3478/udp

- 5349:5349

- 5349:5349/udp

- 49160-49200:49160-49200/udp

command:

- -n

- --external-ip=85.10.207.75

- --use-auth-secret

- --realm=turn.obco.pro

- --static-auth-secret=SECRET

- --listening-port=3478

- --tls-listening-port=5349

- --min-port=49160

- --max-port=49200

- --verbose

- --allow-loopback-peers

- --cli-password=SECRET

- --allowed-peer-ip=10.0.0.1

I really dont know what the problem is. Would be nice if somebody could help me out.
