FirewallBuilder

We start with the firewall object that looks like the one shown on Figure 14.11. This firewall has three interfaces: eth0 (outside), eth1 (inside) and loopback. All addresses are assigned statically. The address of the inside interface "eth1" is 192.168.1.1/24; we also have a network object with name "net-192.168.1.0" that defines the internal network 192.168.1.0/24.

To illustrate generated configurations for platforms other than iptables/Linux in this chapter, I am using similarly configured firewall objects with different platform and host OS settings.
