Port Filtering Web Page (Fig. 28)
This page enables 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 fi ltering, set Start Port and
End Port for each range, and click Apply. To block only one port, set both Start and End ports the
same.
