8.3 Incoming IP Filtering
By default, the ZyXEL Device blocks traffic from the Internet from going to the LAN. Use
incoming IP filtering to allow certain traffic to come in from the Internet to the LAN. For
example, you could allow access to a web server on your LAN to let people access a website
that it is hosting. Click Advanced Setup > Security > IP Filtering > Incoming to open the
following screen. This screen lists the currently configured filtering entries.
