•Default LAN Side Filter: Pass

•Filter Entry: Block

•Protocol: TCP

•IP Address Range: 192.168.123.10 to 192.168.123.20

3.5.2 WAN Filter Settings

Next, access the WAN Filter Settings page by selecting the button from the left-side menu. A WAN Filter works similarly to the LAN Filter. If, for example, you need to run a web server from behind your firewall at your home office, but you only want people in your main office to be able to connect to it, you would want to make the default policy of your WAN Filter Block.

Your setting would look something like this:

•WAN Side Filter Enabled: Enabled

•Default WAN Side Filter: Block

•Filter Entry: Pass

•Protocol: TCP

•IP Address Range: 172.16.203.1 to 172.16.203.254

•Destination Port Range: 80-80 (HTTP)

Click Save to add the filter rule. These settings will allow people in your office (where the IP addresses are in the range indicated) to connect to your web server (since web servers use TCP port 80), but will not allow anyone else to connect.
