Trying to Use Vyatta as Transparent Proxy

Hello.

I am trying to set up a web filter on a network without modifying the addressing structure of my network. I would like to block workstations from accessing websites restricted by a Vyatta webproxy service. However, I do not want to manually configure the workstations.

In a test environment, I can use the Vyatta as a router and transparently perform url filtering and netflow statstics, however I can not wrap my head around how to make this work as a bridge. I have read the bridging is done at the network level but is there a way to simulate bridging using routing/NAT, etc. I would appreciate any help.

In the diagram, rtr address is 192.168.2.1

It's simple enough to setup a bridge on vyata, for example

vyatta@R1# set interfaces bridge br0 address 192.168.2.22/24
vyatta@R1# set interfaces ethernet eth0 bridge-group bridge br0
vyatta@R1# set interfaces ethernet eth1 bridge-group bridge br0
vyatta@R1# commit

Would bridge eth0 & eth1 and give it an IP
