Example: Conguring your rewall to allow for a publicly accessible web server on your LAN
The predened port lter rule for HTTP (TCP port 80) is the same whether the rewall is set to a
high, medium or low security level. To setup a web server located on the local network when the
rewall is enabled, you have to congure the Port Filters setting for HTTP.
As you can see from the diagram below, when the rewall 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

how to add a lter.
