Example: Configuring your firewall to allow a publicly accessible web server on your LAN
The predefined port filter rule for HTTP (TCP port 80) is the same whether the firewall is set to a
high, medium or low security level. To setup a web server located on the local network when the
firewall is enabled, you have to configure the Port Filters setting for HTTP.
As you can see from the diagram below, when the firewall is enabled with one of the three presets
(Low/Medium/High) security level selected, an inbound HTTP access is not allowed which means
remote access through HTTP to your router is not allowed.
Note: Inbound indicates accessing from the Internet to LAN and Outbound is from LAN to
the Internet.
Configuring Packet Filter:
1. Click Packet Filters. You will then be presented with the predefined port filter rules screen (in
this case for the low security level), shown below:
Note: You may click Edit the predefined rule instead of Delete it. This is an example to show
to how you add a filter on your own.
