View Full Version : [ubuntu] 12.10 unable to create functional bridge

January 12th, 2013, 06:21 AM
Dell Poweredge 2950, dual physical eth devices. Eth0 is DMZ'd and gets a DHCP address from the public network router. Eth1 has an internal static IP, allowing the server to be used as a Squid transparent proxy. Additional services include Shorewall, Samba (as PDC), and SSHd. When I create a bridge manually, I lose public and private connectivity as well as internet connectivity from the private network.

Here is what I run in bash:

ifconfig eth1 down
ifconfig eth1 up promisc
brctl addbr br1
ifconfig br1 192.168.x.x
ifconfig br1 netmask
brctl addif br1 eth1
ifconfig br1 up

I don't know where the issue is. I changed shorewall's interfaces and masq files to reflect br1 instead of eth1, but still cannot reach either the public or private networks when br1 takes over.

End result desired is a auto-configured bridge that I can use with LXC containers to have individual local addresses on my network.
