# IP’s and Port’s to be Whitelisted in case of Firewall restrictions

* **IP whitelisting**(allowlisting) entails creating a list of trusted IP addresses (dedicated static IP addresses are required), assigning them to a user or group of users as a unique identifier, and allowing the IP address to be used only on the target server.

### Typically, IP whitelisting is handled on:**Edge routers**- typically set up to block undesired traffic on router's TCP and UDP port in order to protect internal LAN from the public internet threats **Firewall**- configured to grant access to the network only to specific users/devices/LANs \*\* Business VPN gateway **Web serve** r - typically to manage incoming requests and prevent extensive malicious requests (brute force attacks)**Application layer**- incoming queries can be evaluated and blocked/allowed by design in the code of the application \*\* SaaS application \*\*- SaaS apps usually allow setting up IP whitelists to harden security measures.

The firewall should allow outgoing UDP to the public internet from the browsers that use **Salesmate Calling**, and allow return traffic in response.

For the **static IP range for UDP**, please open up the traffic to the following **CIDRs**. You have to open up traffic to all the CIDRs mentioned below. Twilio will dynamically connect to one of these IP ranges depending on the browser location.
