#### Firewalls or NAT

Note: Not yet implemented.
|

|

If your mumble-web-proxy is running behind a firewall or NAT, you need to allocate a range of ports to it which it can use for ICE connection establishment.
|
||||
```
|
||||
mumble-web-proxy --listen-ws 64737 --server mumbleserver:64738 --ice-start 20000 --ice-end 21000

|
||||
```
|

For NATs, you additionally need to provide it with its publicly reachable IP address(es):
