Diameter Maintenance Signaling Firewall

The Signaling Firewall feature provides network security for Diameter networks in LTE domains. This feature configured with firewall rules by the System OAM only operates on DA-MP servers. When you enable or disable a diameter or RADIUS connection, a notification is sent to the servers to update the firewall rules to allow or disallow incoming network traffic.

Note: In new DSR installations, the Signaling Firewall is enabled by default; however, during a DSR upgrade without the feature, the Signaling Firewall is disabled by default. Otherwise, it uses the setting from the previous release.
