Billion BIPAC-7500G–802.11g ADSL VPN Firewall Router with 3DES Accelerator

Example: Configuring your firewall to allow for a publicly accessible web server on your LAN

The pre-defined port filter rule for HTTP (TCP port 80) is the same no matter 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), inbound HTTP access is not allowed.
