Define the authorized data transmitting rate and drop all other
unauthorized hosts.
Note:
If we setup IP blacklist rules here, those unauthorized hosts will still be
able to send SIP packets into MyPBX if the packets transmitting rate is under the
rate defined. But as soon as the transmitting beyond the define rate, the IP will
be added into blacklist automatically.
This is useful for remote extension who is using dynamic IP address.
Remove all the IP blacklist rules if you don‟t allowed any other unauthorized
hosts access MyPBX.See as below figure.
Note:
If „drop all‟ is not enabled, please don‟t remove the IP blacklist rules in
case the system security hole.
