Hi, I have a Linux box in the border of a customer and have the following setup: Eth0 - ADSL with dinamic IP Eth1 - Internet conn with 6 IP available eth2 - Internal net 1 eth3 - internal net 2 This box runs Squid, in transparent mode. I redirect all traffic to internet on port 80 to port 3128 on the box, when coming from eth2 and eth3. I need to make all traffic from eth2 and eth3 get to the Internet through eth0 and the traffic the firewall origintates too. Only traffic recieved from a single host in eth3 and coming from eth1 should get out through eth1. how can I acomplish this? ===== Marcelo de Azevedo Rosa Consultor/Instrutor em Tecnologias de Rede Network Technologies Consultant/Instructor - CCDA/CCNA/CCSI/MCNE GnuPG (www.gnupg.org) - Key ID: 0xFE26FC98 Key fingerprint = B055 B875 67FB 40A3 FBBF A1CB 903D DBB0 FE26 FC98 http://signature.coola.com/?marcelorosa2000@xxxxxxxxxxxx ______________________________________________________________________ Yahoo!
