4.7.2 LAN Isolation 
LAN isolation allows you to disable the flow of packets up to three user-defined LAN groups 
(WLAN, USB, and Ethernet). This allows you to secure information in private portions of the 
LAN from other publicly accessible LAN segments.

4.7.3 URL Filters 
This feature allows the router to block access to certain websites by examining its URL, a text 
string describing a unique location on the Internet. If the URL contains a blocked keyword, then 
access to that website will be denied. See Figure 1-67.
