Filtering
This page allows you to enter ranges of destination ports (applications) that you don’t want your LAN
PCs to send packets to. Any packets your LAN PCs send to these destination ports will be blocked.
For example, you could block access to worldwide web browsing (http = port 80) but still allow email
service (SMTP port 25 and POP-3 port 110). To enable port filtering, set Start Port and End Port for
each range, and click Apply. To block only one port, set both Start and End ports with the same value.
