All of the physical devices can be individually configured and can be assigned to internal, dmz, or external
zones in the firewall.
One or more physical interfaces can be combined into a single logical interface (br0). The logical interface is
like an Ethernet switch and MAC address to physical port mappings are typically remembered for up to 5
minutes before traffic for a given address is broadcast to all ports again.
The following shows an example of configuring Ethernet ports 0-2 and wlan0 as a single bridged interface,
the DHCP range is set to 100 addresses from 100 to 199 and the interface is assigned to the internal zone
on the firewall. The Wi-Fi SSID is set to "imo" and the shared key is "12345678":

Ethernet port 3 is configured for a separate subnet with its own DHCP range. Unless a routing rule is added
in the [fw] section, no data will be routed between the 192.168.0.0/24 and 192.168.100.0/24 subnets.
