Hi guys, first I'm a big Linux noob but I have done some reading and research and have found not much concerning my problem. I realy hope you guy's can help me.

Well, I have a Linux opensource Suse10.3 installed on a entry level P4, Webmin-1.410, Squid3.0.STABLE4 and build only for transparent caching purposes. It is setup with 1 router and 1 local win vista pc and working great --(except for cachemrg.cgi that's missing?!?)

Anyway, the br0 I have with port='eth0 eth1' is working great and setup according these instructions:

1. At the console login as root.
o This step will disconnect the server enough to stop a remote session, so this has to be done at the server.
2. Install Brigde-Utils first:
o yast -i bridge-utils
 You may be asked for the install media.
3. Go to the network folder:
o cd /etc/sysconfig/network
 Note that interface set-up information is in configuration files that are preceded by 'ifcfg-<interface name>' and will be auto loaded based on that naming standard.
4. Backup the network configuration by making a folder and copying the contents there:
o mkdir ../network.old
o cp -Rv * ../network.old
5. Remove the existing configuration:
o rm ifcfg-*
 This will not kill the network connection till the service is reloaded and the configuration files are re-read
6. Create a new configuration file as such:
o touch ifcfg-br0
 This creates a blank file of given name.
o gedit ifcfg-br0
 At a terminal session from inside Gnome (the desktop) this starts the text editor. Create a file that looks like this:

STARTMODE=auto
BOOTPROTO=static
IPADDR=YourValidIPAddress
NETMASK=YourValidNetMask
BRIDGE='yes'
BRIDGE_PORTS='eth0 eth1'
BRIDGE_AGEINGTIME='300'
BRIDGE_FORWARDDELAY='0'
BRIDGE_HELLOTIME='2'
BRIDGE_MAXAGE='20'
BRIDGE_PATHCOSTS='19'
BRIDGE_STP='on'
7. Restart networking:
o /etc/init.d/network restart
 If there were no typos in the file, things should be up and running and the address above can be reached across the LAN.

Now, my problem is that I have two Routers, 1 Cisco and 1 Billion routers with their own set of static ip's provided by the isp's. Here is a small pic I drew up showing a bit more detail:



How do I setup a bridge between 3 network interfaces, or is there maybe a other solution.
Thanks in advance!

ps: the more I play with Linux, the more I like it.
Keep up the good work guy's, cheers.
