2. Firewall configuration
Note: Please back up the configurations on Backup and Restore page before you go
ahead. In the case that you lock the device, you can reset to factory default and restore
the previous configurations. The example rules below work with MyPBX firmware version
2.15.xx.xx or higher versions.
The basic logic to configure firewall is “Allow all trusted IP addresses and then
enable “Drop All””.
Step1. Enable firewall on firewall page of MyPBX.

Step2. Add common rules to accept local network access.
Create a common rule to allow all the IP addresses of the local phones to access MyPBX
server. For example, the local IP range is 192.168.5.1-192.168.5.254, the configuration
could be as below:
Name: LocalNetwork
Protocol: BOTH
Port: 1:65535
IP: 192.168.5.0/255.255.255.0, the format must be “IP/net mask”
