URL Blocking

Use URL Blocking to define rules to block or allow incoming and outgoing Web request packets. The rules can control the
Web requests containing complete URLs, partial domain names, or pre‐defined keywords. For example, you can filter out or
allow only Web requests containing domain suffixes like .com, .edu or .org or keywords like "torrent" or "warez".
Each rule is designated either as a Black List, blocking access from defined addresses, or a White List which specifically allows
access.
In addition to rule parameters regarding addresses and keywords, rules can be set to run on schedules and the blocking activity
can be logged, monitored and reported.

URL Blocking Rule with Black List

When the administrator of the router wants to block Web requests with dedicated patterns, they can use the "URL Blocking"
function to block specific Web requests by defining the black list as shown in the diagram above. When the administrator
wants to allow only Web requests with dedicated patterns to go through the router, they can also use the "URL Blocking"
function by defining the white list to meet the requirement.
