Let me see if I understand what you attempt to do. In your pc you have 2 networks adapters and want to made a temporal bridge between both, if is that the case an iptables rule should do the work in an easiest way. But if it has to be permanent this documentation can help you [1] but you have to remember “Don't set the IP address, and don't let the startup scripts run DHCP on the Ethernet interfaces either. The IP address needs to be set after the bridge has been configured.” Maybe because that the bridge isn’t working right for you.

Hello,
How can I use network manager so that I can plug my girlfriends laptop into port 1 of my computer, while port 0 is plugged to the loooong cable that goes back to my encore 8 port switch and from there to my DSL modem?
I have tried to use bridge-control tools, and also acitvated packet forwarding like this: echo "1" > /proc/sys/net/ipv4/ip_forward
I think the problem is around here:
me@pc:~$ ifconfig
eth1 Link encap:Ethernet HWaddr 04:4b:80:80:80:03
inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: fe80::64b:80ff:fe80:8003/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
eth0-eth1 Link encap:Ethernet HWaddr 04:4b:80:80:80:03
UP BROADCAST MULTICAST MTU:1500 Metric:1
See how the 2 ports have same MAC? How can I configure network manager to handle 2 different ports? And how would I go about configuring it to route packets out to the internet coming from my chicks's laptop?
Ubuntu 10.10
Asus Crosshair mobo version 1
Thanks,
