Currently, it is not supported to supply multiple NAT addresses directly to neko (see https://github.com/m1k1o/neko/issues/47).
But it can be acheived by deploying own turn server alongside neko that is accessible from your LAN:
```yaml
version: "3.4"
services:
neko:
image: "m1k1o/neko:firefox"
restart: "unless-stopped"
shm_size: "2gb"
ports:
- "8080:8080"
- "52000-52100:52000-52100/udp"
environment:
NEKO_SCREEN: 1920x1080@30
NEKO_PASSWORD: neko
NEKO_PASSWORD_ADMIN: admin
NEKO_EPR: 52000-52100
NEKO_ICESERVERS: '[{ "urls": [ "turn:192.168.1.60:3478" ], "username":"neko", "credential":"neko" }, { "urls": [ "stun:stun.nextcloud.com:3478" ] }]'
coturn:
image: 'coturn/coturn:latest'
network_mode: "host"
command: |
-n
--realm=localhost
--fingerprint
--listening-ip=0.0.0.0
--external-ip=192.168.1.60
--listening-port=3478
--min-port=49160
--max-port=49200
--log-file=stdout
--user=neko:neko
--lt-cred-mech
```
- Replace `192.168.1.60` with your LAN IP address, and allow ports `49160-49200/udp` and `3478/tcp` in your LAN.
- Make sure you don't use `NEKO_ICELITE: true` because ICE LITE does not support TURN servers.
This setup adds local turn server to neko. It won't be reachable by your remote clients and your own IP won't be reachable from your lan. So it effectively just adds local candidate and allows connections from LAN.
### Why so many ports? ### Why so many ports?
- WebRTC needs UDP ports in order to transfer Audio/Video towards user and Mouse/Keyboard events to the server in real time. - WebRTC needs UDP ports in order to transfer Audio/Video towards user and Mouse/Keyboard events to the server in real time.

If your router does not support NAT Loopback (NAT Hairpinning), you can use turn servers to overcome this issue. See [more details here](https://neko.m1k1o.net/#/getting-started/?id=networking) on how to setup local coturn instance.
