# Network Rules

You may find that you are on a strictly regulated network, in this case Web Comms wont be able to connect to the rooms without certain web addresses being allowed through the firewall.

Should you experience connectivity issues, make sure that the following urls are whitelisted and contactable from the PC you are using Web comms on:

```
https://rtc.webcomms.net/
```

```
https://rtc-turn.webcomms.net/
```

```
https://whip.webcomms.net/
```
