Firewall Policy
Firewall policy examples
The proposed network is based around a ForitGate 100A unit. The 15 internal
computers are behind the FortiGate unit. They now access the email and web
servers in a DMZ, which is also behind the FortiGate unit. All home based
employees now access the office network through the FortiGate unit via VPN
tunnels.
Scenario two: enterprise sized business
Located in a large city, the library system is anchored by a main downtown
location serving most of the population, with more than a dozen branches spread
throughout the city. Each branch is wired to the Internet but none are linked with
each other by dedicated connections.
The current network topography at the main location consists of three user
groups. The main branch staff and public terminals access the servers in the DMZ
behind the firewall. The catalog access terminals directly access the catalog
server without first going through the firewall.
The topography at the branch office has all three users accessing the servers at
the main branch via non secured internet connections.

The library must be able to set different access levels for patrons and staff
members.
