ups sorry, forgot to change the subject is it possible to use 2 internet connection with 1 instance of squid? ( some what like load balancing ) so the pc has 3 eth, eth0 is connected to LAN, eth1 to ISP1 and eth2 to ISP2 or only 2 eth used, eth1 is bind to 2 different IP, to enable to connect bith ISP1 and ISP2 But what setting should be done for the squid to use both ?
