Single to Double NIC

When switching from a Single NIC setup to using dual NICs, Changes need to be made in several places.

• Web Admin: Advanced menu > Network > Network Settings (more or less optional) (WARNING: one test of this step caused unexpected network operation Matthew 07:15, 18 December 2007 (MST)).
• Web Admin: Show devices tree/My Devices/CORE > Device data/Network Interfaces
  • Change: eth0,dhcp|eth0:0,192.168.80.1,255.255.255.0 to: eth0,dhcp|eth1,192.168.80.1,255.255.255.0
• /etc/network/interfaces (can be edited from the launch manager).
  • Comment out eth0:0 related entries:

auto lo
        iface lo inet loopback
        address 127.0.0.1
        netmask 255.0.0.0


iface eth0 inet dhcp
#auto eth0:0
#iface eth0:0 inet static
#       address 192.168.80.1
#       netmask 255.255.255.0
    */ This sets eth0 to use DHCP to connect to cable/DSL/etc. automatically */
iface eth1 inet static
address 192.168.80.1
netmask 255.255.255.0
    */ This sets eth1 to use the internal network */
auto eth1

auto eth0

• You may need to edit /etc/iftab as well and add a line similar to the eth0 one for your new eth1 with it's own unique MAC address. See man iftab for more details on this file.
