The index numbers in the table above may change according to your specific allow
and block rules.
The last rule (Index 18) is an example of a blocking traffic rule (blocks all other
traffic).
Configure the firewall on the Active device. This configuration is automatically
applied to the Redundant device.
If you have an external firewall located between the Active and the Redundant HA
Maintenance interfaces, you must open (allow) the same port ranges as configured
in the table above, on that external firewall.
If the device needs to communicate with AudioCodes OVOC, you must also add
rules to allow incoming traffic from OVOC. For more information, see
Firewall Rules to Allow Incoming OVOC Traffic
