### The example in this directory consists of the following
### network topology.

A central firewall with 3 interfaces running dwall.

Each interface has a different network (zone) and is named resp.
internet (eth0), dmz (eth1) and local (eth2).

The internet zone is a connection to internet using interface eth0.
The default gateway points to a system on this interface.

The dmz zone is a demilitarized zone and is connected to interface
eth1. It has a public webserver and a public mailserver connected
to it. The network range is 10.0.1.0/24

The local zone is connected to interface eth2 and consists of
3 network ranges 10.0.2.0/24, 10.0.3.0/24 and 10.0.4.0/24 resp.
servers, admins and clients.

The firewall is configured to allow specific network traffic
between the different zones (or no traffic at all). Both the
local zone as the dmz zone are masqueraded from the internet.
