Billion BiPAC 8500/8501/8520/8521 SHDSL (VPN) Firewall Bridge/ Router
Chapter 4: Configuration
87
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 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
