# Firewall Access Rules

If your organization uses a firewall or network security policy, you may need to allow access to specific domains and ports for Coresee to work properly. This article covers everything your IT team needs to configure network access.

## **Domain**

All Coresee traffic runs through: [**app.coresee.com**](http://app.coresee.com)

It uses these 2 static public IP addresses: 

* 54.188.204.120
* 52.26.192.139

## **Required Ports**

Configure your firewall to allow the following:

| **Protocol** | **Port** | **Purpose** |
| :-: | :-: | :-: |
| TCP | 443 | HTTPS, RTSP, RTMP, and TURN |
| TCP + UDP | 3478 | STUN and TURN |
