[tproxy] Admin interfacer por tproxy bridge

[Federico Alberto Sayd]

Hello:

I am setting up a tproxy on a bridge. I need to sit the tproxy in a 
network segment whitout public internet range to catch connections from 
2 public networks that route through 2 ISP.
Documentation for Tproxy4 (http://wiki.squid-cache.org/Features/Tproxy4) 
says I need a public addres configured on the bridge interface. Obviusly 
I cant assign a public addres on the bridge interface.

I have another interface for administration but when I configure with 
public ip address, routing fails and the packets aren't redirected to 
Squid and connections timeouts.

Documentation mentions troubles related to bridges with admin 
interfaces, the doc mentions extra configurations about default routes.

The network configuration is the next

                                                                         
                             Router ISP 1
Org net (2 public nets) == Router ==Tproxy-Bridge==Switch=            
         == Internet
                                                                         
                             Router ISP 2

                                                      ^^^^^^^^^^^^^^^^^^
                                                             
Private      network


How I can configure a third inteface to administrate the tproxy bridge? 
What parameters I have to modify in order the packets to be routed 
correctly?

Thanks, and sorry for my poor english
