This is where you can configure those web sites that are to be blocked.
Telnet path: /Setup/UTM/Content-Filter/Profiles
Note: Entries for the forbidden web sites may contain up to 252 characters. To define longer blacklist entries, a number of entries can use a special, shared name. Enter the name of the blacklist followed by a # character and any suffix. For example, you create three blacklist entries called "MyBlacklist#1", "MyBlacklist#2" and "MyBlacklist#3". In the content filtering profile, you can reference this extended blacklist with the name "MyBlacklist".
