Protocol: BOTH
Port: 1:65535
IP: 192.168.5.0/255.255.255.0

Step3. Create common rules to accept remote extensions or remote
administrators, if you use SIP trunk, please accept the provider‟s host as well.
Note: If there are no remote extensions, the rule is not required.

access MyPBX server. e.g.110.111.132.6, the configurations could be as
below:
Name: Remote Extension
Protocol: BOTH
Port: 1:65535
IP: 110.111.132.6/255.255.255.255
