Whitelisting Intercom on your firewall

Whitelisting Intercom on your firewall involves allowing specific network traffic from Intercom's services to pass through your firewall. This is typically done to ensure that Intercom's communication with your servers or devices is not blocked by your firewall's security settings.

If you discover that your firewall is constantly blocking or otherwise preventing you from accessing Intercom, you may want to whitelist your IP address. Firewalls are designed to keep malicious traffic out of networks. But legitimate traffic can get caught in the crossfire.
