Network interfaces

Network configuration is specified in /etc/network/interfaces. This example configures the WAN on eth0 and the WLAN on wlan0 which is just enough to get up and running. Other LAN interfaces will be added later.

root@voyage:~# cat /etc/network/interfaces

auto lo

iface lo inet loopback

auto eth0

 iface eth0 inet dhcp # assigns dynamic address on WAN interface

 post-up pon eircom   # starts eircom PPPoE session after interface is up

auto wlan0

iface wlan0 inet static

 address 192.168.11.254

 netmask 255.255.255.0

 broadcast 192.168.11.255

 hostapd /etc/hostapd/hostapd.wlan0.conf # configures WLAN interface

 up nat.sh wlan0 eth0 “192.168.11.0/24"  # configures NAT

The script etc/init.d/hostapd is run at startup and applies WLAN settings specified in /etc/hostapd/hostapd.wlan0.conf
