Installing a Cerberian license key
Before you can use the Cerberian web filter, you must install a license key. The
license key determines the number of end users allowed to use Cerberian web
filtering through the FortiGate unit.
To install a Cerberian licence key
1 Go to Web Filter > URL Block.
2 Select Cerberian URL Filtering.
3 Enter the license number.
4 Select Apply.
Adding a Cerberian user
The Cerberian web policies can be applied only to user groups. You can add users on
the FortiGate unit and then add the users to user groups on the Cerberian
administration web site.
When the end user tries to access a URL, the FortiGate unit checks whether the
user’s IP address is in the IP address list on the FortiGate unit. If the user’s IP address
is in the list, the request is sent to the Cerberian server. Otherwise, an error message
is sent to the user saying that the user does not have authorized access to the
Cerberian web filter.
To add a Cerberian user
1 Go to Web Filter > URL Block.
2 Select Cerberian URL Filtering.
3 Select New.
4 Enter the IP address and netmask of the user computers.
You can enter the IP address of a single user. For example, 192.168.100.19
255.255.255.255. You can also enter a subnet of a group of users. For example,
192.168.100.0 255.255.255.0.
5 Enter an alias for the user.
The alias is used as the user name when you add the user to a user group on the
Cerberian server. If you do not enter an alias, the user’s IP is used and added to the
default group on the Cerberian server.
6 Select OK.
Configuring Cerberian web filter

users to the user groups on the Cerberian web filter server. Then you can create
policies and apply these policies to the user groups.
About the default group and policy
There is a default user group, which is associated with a default policy, that exists on
the Cerberian web filter server.
