VoIP/(802.11g) ADSL2+ (VPN) Firewall Router
Example: Configuring your firewall to allow for a publicly accessible web server on your LAN
The predefined 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 which means remote access through HTTP to
your router is not allowed.
(Note: Inbound indicates accessing from Internet to LAN and Outbound is from LAN to the Internet)
