While there is no shortage of documentation on setting up a
transparent bridge with Squid proxy, I have only seen examples that
assign an IP address to the bridge interface. In my circumstances,
the bridge is between the ISP's bridge and our own router, such as:
(ISP Bridge) <--->(Our Bridge)<--->(Our router). Typical I'm sure,
but Our router is assigned only 1 IP address so I really don't have an
IP address to assign the bridge interface. Here's how I'm setup:
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth1
ip link set br0 up
# Normally, would assign an IP address to br0 and a default route
I was thinking I should be able to re-direct to the localhost
interface 127.0.0.1, or perhaps assign an address like 127.0.0.2 to
br0, but then could not figure out the appropriate iptables and route
command. I'm sure I could assign br0 a private ip address, but then
wouldn't be sure how to tell it to route. Here's all I have so far...
ebtables -t broute -A BROUTING -p IPv4 --ip-protocol 6 \
--ip-destination-port 80 -j redirect --redirect-target ACCEPT
If I've completely missed where this has been addressed somewhere else
I'd appreciate a link or some advice here.
Thanks!
