This screen is divided into two identical sections, one for 'Input Rule Sets' and the other for
'Output Rule Sets', which are for configuring inbound and outbound traffic, respectively.
Each section is comprised of subsets, which can be grouped into three main subjects:
1. Initial rules - rules defined here are applied first, on all devices.
2. Network devices rules - rules can be defined per the device.
3. Final rules - rules defined here are applied last, on all devices.
Numerous rules are automatically inserted by the firewall to provide improved security and
block harmful attacks.
Note: The order of appearance of the firewall rules determines the sequence by
which they are applied.
To configure an advanced filtering rule:
1. After choosing the traffic direction and the device on which to set the rule, click the
corresponding link New Entry; the screen 'Add Advanced Filter' opens.
