Chapter 5. Security
This chapter will introduce you how to configure the Security of PLANET IP PBX.
5.1 Firewall
The IP PBX system has been preconfigured with a built-in firewall which prevents your IP
phone system from unauthorized accessing, phone calls and some other attacks.
General
Item Explanation
Enable Firewall By default, firewall is enabled. You may disable the built-in firewall by
unchecking “Enable Firewall” checkbox, only if your IP PBX is behind
a router/firewall without port forwarding to the Internet.
Disable Ping Ignore ping request. If enabled, you cannot ping the IPPBX system.
Drop All Drop all packets sent to the IP PBX system, this will cause IP PBX
system blocking all communication with the outside world. So the
system will prompt to add at least one grant rule on port 22 (SSH) or
9999 (Web) to make sure the IPPBX system is totally unreachable.
The rule/rules can be created in the “Common Rules” section.
Common Rules
In Common Rules section, you can configure the firewall to grant or deny an IP address or a
network from communicating with the IPPBX system. Even the service port number can be
specified so it can grant or deny a specific IP or network to access a specific service.
