Connection Map

The following diagram illustrates integration points. The point of the diagram is to show that you need to review IPs and Ports for connections into and out of your environment. The connections that are used by Webex for Cisco BroadWorks are described in the subsequent tables.

The firewall requirements for the normal functioning of the client application are listed as references since they are already documented on help.webex.com.

Firewall Configuration

The connection map and the following tables describe the connections and protocols required between the clients (on or off the customer’s network), your network, and the Webex platform.

We recommend that you configure your firewall to allow traffic to the NPS proxy FQDN instead, to ensure that your egress is only towards the hosts we expose for NPS proxy.

* APNS and FCM do not have a fixed set of IP addresses.
