4.5 Configuring Content Filtering

You can use the ZyWALL's content filtering policies to apply specific content filtering
settings to specific users. You can even filter certain things at certain times. For example, you
decide to set the default policy to block access to several categories of web content including
things like pornography, hacking, nudity, and arts and entertainment, and so on. Now, suppose
you want to allow an employee named Bob to access arts and entertainment web pages during
lunch. You can create another policy for traffic from Bob's computer.
The ordering of your policies is very important as the ZyWALL applies policies
in the order they are listed.
The ZyWALL applies the content filter policies based on the source address and the schedule.
So for this example, when the ZyWALL receives a request from the LAN for a web page, it
checks the request against the first policy. If the traffic matches (that is if it is from Bob's
computer and the time is between 12:00 and 13:00), the ZyWALL applies the first policy. Any
traffic that does not match the first policy will match the default policy and the ZyWALL
treats it based on the default policy.
