Thread: Multiple NICs Not Working Properly

my setup:

i've looked around answer , haven't found 1 did help.

set isc-dhcp-server software on kubuntu 11.04 box , receiving issue saying no connection bound eth3 (my pci nic). eth0 onboard. eth1 , eth2 physically removed system.

edited /etc/network/interfaces file. following entry:

code:

auto lo iface lo inet loopback

oddly enough, eth0 working fine. added following:

code:

auto eth3 iface eth3 inet static address 192.168.1.4 subnet 255.255.255.0

now here's issue shows up:

eth0 won't accept connections. shows on router setup page doesn't have correct name in "attached devices" area , isn't getting ip should getting.

eth3 accepts local connections (ssh , like) when try connect internet, nothing when eth3 connection used router.

when add following line /etc/network/interfaces file

code:

auto eth0 iface eth0 inet dhcp

the following appears in ifconfig

code:

eth0:avahi link encap:ethernet  hwaddr 00:30:67:6c:e5:6a             inet addr:169.254.8.233  bcast:169.254.255.255  mask:255.255.0.0           broadcast multicast  mtu:1500  metric:1           interrupt:41 base address:0x6000

the overall goal need eth0 internet , eth3 serve dhcp connections can image machines/network boot off of eth3 , still have internet access through eth0.

have change make work?

if need additional information, please let me know.
