Hi Team,

**Issue Summary:**

As we attempted to run the STUN server with GenieACS but were unable to bring the device online.

**Investigation and Actions Taken:**

1. **Configuration Updates:**

- Edited the genieacs.env file at /opt/genieacs/genieacs.env
- Added the following entries to configure the UDP connection request port:

ini

```auto
UDP_CONNECTION_REQUEST_PORT=3478  
GENIEACS_UDP_CONNECTION_REQUEST_PORT=3478  

```

1. **STUN/TURN Server Setup:**

- Installed `coturn` to handle STUN/TURN server requirements:

arduino

```auto
apt-get install coturn  
systemctl status coturn  
systemctl start coturn  
systemctl stop coturn  

```

- Configured /etc/turnserver.conf with the following settings:

perl

```auto
listening-port=3478  
tls-listening-port=5349  

fingerprint  
lt-cred-mech  

use-auth-secret  
static-auth-secret=67a95d4e912e6702d6831ab5fbf269978004b2a3fb9b254523dc0b69015d9e79  

realm=turn.example.com  

total-quota=100  
stale-nonce=600  

cert=/etc/letsencrypt/live/turn.example.com/cert.pem  
pkey=/etc/letsencrypt/live/turn.example.com/privkey.pem  
cipher-list="ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384"  

no-sslv3  
no-tlsv1  
no-tlsv1_1  

dh2066  

no-stdout-log  
log-file=/var/tmp/turn.log  

no-loopback-peers  
no-multicast-peers  

proc-user=turnserver  
proc-group=turnserver  

```

1. **GenieACS Configuration:**

- Updated genieacs.env with:

ini

```auto
GENIEACS_STUN_SERVER=<serverIP>:3478  

```

**Error Details:**  
The device remains offline with the following status:  
`<device info>: Device is offline`  
Screenshot attached:

**Current Status:**  
Despite these configurations, the device is still offline when connecting to the ACS.

We would appreciate any insights or recommendations to resolve this issue.

Struggeling with the same problem as there is little to no documentation how to use STUN properly. I use the 1.2.13 and fiddled together a container for myself with drumsergio’s container and an included stuntman so it’s runnning in the same container. I set the cwmp.udpConnectionRequestPort to 3478 in Admin → Config and I have a populated InternetGatewayDevice.ManagementServer.STUNEnable to true and a populated InternetGatewayDevice.ManagementServer.UDPConnectionRequestAddress with a correct IP and port it got from the STUN server on the CPE.

I enabled debugging for this explicit CPE and I see 3 times this event (masked for privacy):

```auto
event: outgoing UDP message
timestamp: 2025-03-01T16:06:37.114Z
remoteAddress: x.x.x.x
deviceId: 1449BC-Vigor2135FVac-1449BCXXXX
remotePort: 46838
body: "GET http://x.x.x.x:46838?ts=1740845197&id=3247567587&un=acs-cpe&cn=de9839c1ddxxxxxx&sig=6bf0bfd6055358ee1708dce87700e8cc4dxxxxxx HTTP/1.1\r\nHost: x.x.x.x:46838\r\n\r\n"
---

```

Which results in a “No contact from CPE” after the timeout.

I don’t know if it is an CPE- or acs-issue and there is this thread [GenieACS works with STUN](https://forum.genieacs.com/t/genieacs-works-with-stun/6107) which points to acs

I’ve the same issue with version 1.2.13. Downgraded to 1.2.9 and devices with STUN works fine.

```auto
 cd /opt/genieacs
 npm install -g genieacs@1.2.9

```
