If you wish to set an interface for static IP addressing, then use the

following configuration. Each interface must be configured with separate

entries in the network/interfaces file; LAN1 corresponds to eth0, LAN 2

corresponds to eth1, and so forth for the remaining interfaces.

# The loopback network interface

auto lo

iface lo inet loopback

# The first LAN interface, LAN 1

auto eth0

iface eth0 inet static

address 192.168.3.127

netmask 255.255.255.0

broadcast 192.168.3.255

# The second LAN interface, LAN 2

auto eth1

iface eth1 inet static

address 192.168.4.127

netmask 255.255.255.0

broadcast 192.168.4.255

Exit VI by typing:

:wq

After the interfaces file has been configured, use the following commands

to reinitialize the network interfaces and activate the new settings

immediately:

#sync; ifup –a
