Adding User Defined Ports
If a port is not listed it may be entered manually by entering the port number in User Defined Ports. A range of ports may be entered by using range:range.
Enabling All Ports
Enabling all ports opens all ports. This is the default setting of NetPurifier.
Router Compatibility Mode
NetPurifier uses latest generation Statefull Packet Inspection (SPI) to determine ports that should be opened or closed in response to settings in Common Ports. This allows programs that are wanted to be let through and programs that are not wanted to be blocked. Older generation routers are not aware of this technology and may not operate properly with Port Blocker. If certain applications (such as email or FTP) do not work as expected after configuring port blocker then there may be a router compatibility issue.
If such an issue is determined there are two courses of action that may be followed.
Enable Router Compatibility mode. This mode allows only Port 80 to be open. Web access is allowed. All other ports are blocked.
Enable all Ports. This will open all ports and allow all applications to connect.
