Customizing the firewall
To customize the firewall, you define one or more rules. A rule lets you target a specific type
of data traffic. If the service controller finds data traffic that matches the rule, the rule is
triggered, and the traffic is rejected or accepted by the firewall.
To add a rule, select Custom Firewall on page Security > Firewall, select Edit, and then
select Add New Rule.
Rules operate on IP datagrams (sometimes called packets). Datagrams are the individual
packages of data that travel on an IP network. Each datagram contains addressing and
control information along with the data it is transporting. The firewall analyses the
addressing and control information to apply the rules you define.
The service controller applies the firewall rules in the order that they appear in the list. An
intelligent mechanism automatically adds the new rules to the list based on their scope. Rules
that target a large amount of data are added at the bottom. Rules that target specific datagram
attributes are added at the top.
