squid+bridge+2 subnet - My network Dia inside

Hi there,

My first post....

There's a situation where i need to have my Linux Bridge/Squid firewall with traffic from 2 subnets.

My network is,
   ISP---router1-|   |--router0--ISP
                 |   |
            |  link proof(LP) |
              |       |
              |       |  
              |       |
              |    ---|------
              |   |   PIX    | 
              |    ---|------
              |       |
              |       | int 0
              |   ----|----------------------
        int 2 |--| Linux Bridge/Squid |
                         |int 1
              | Layer 3 switch|
                  |        |
        ----------|-----   |
       | n/w|  |
        ----------------   |    ----------------
            LAN            |---| n/w |   

I am trying to configure linux bridge/squid, traffic should go through int0,pix,LP,router0 and traffic should go through int2,LP,Router1. My Layer 3 switch has a limit, it can't do a source based routing. Link Proof device is failover device. The Link Proof has public IP at the outside interface and does NATing.

I have set the the Linux with shorewall, without redirecting port 80 to squid, browsing happens and everything works fine from both the network, I have a problem with Squid. Squid currently is working for network but not for subnet, ie., Squid is working from int 1 to int 2, but how to I make squid work with int1 to int2 as well. ie., Any traffic from subnet squid should filter and put it to int0 and Any traffic from subnet squid should filter and put it to int2.

Very Urgent,Can anyone please help...
Thanx in advance...

The picture seems to be not proper in the post, please mail me I can send it through mail...

Sorry this doesn't answer your question.

If you wrap your acsi art in the code tags then it will come out as you wanted.

To get code tags you can use the # button on the little toolbar when you use the advance mode. Or you can type the like this,

stuff in here

Below is an example. Both of them were typed out to look the same when i wrote this reply
