Yeah, I think you want bridge-utils. Here's one way to set this up,
but you'll probably have to do this from the serial console.


brctl addbr br0

ifconfig eth0 down
ifconfig eth1 down
ifconfig eth2 down
ifconfig eth3 down

brctl addif br0 eth0
brctl addif br0 eth1
brctl addif br0 eth2
brctl addif br0 eth3


ifconfig br0 192.168.10.50

ifconfig eth0 0.0.0.0 up
ifconfig eth1 0.0.0.0 up
ifconfig eth2 0.0.0.0 up
ifconfig eth3 0.0.0.0 up

# you'll need to assign your gateway here
# I'm just guessing it's 192.168.10.1
GATEWAY=192.168.10.1
route add default gw $GATEWAY br0

# For testing, take down the firewall
iptables -F
# If you need firewall on bridge here is an example.
# You'll need to check that bridge module for iptables is loaded
#iptables -A INPUT -i br0 -p tcp --dport 111 -d 192.168.1.120 -m physdev  --physdev-is-in -j DROP


I think there are also some notes on (TIP 263) in the following
link. Plus there may be some notes simple traffic shaping.

Hope this helps.
