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 will be applied first, on all gateway devices.
2. Network devices rules - rules can be defined per each gateway device.
3. Final rules - rules defined here will be applied last, on all gateway devices.
Note: The order of the firewall rules' appearance in the screen 'Advanced Filtering'
represents the sequence by which they will be applied.
Numerous rules are automatically inserted by the firewall to provide improved security and
block harmful attacks.

appropriate link 'New Entry'; the screen 'Add Advanced Filter' opens (refer to the
