Hi Thanks to all for the answers. I will tell you my confguration. I have a debian etch box with 2 network interfaces. One for WAN and the other LAN. I have an script with iptables to redirect traffic to the proxy as transparent proxy. When I started the Squid service, the ping after 10 or 15 minutes fails. When I stopped the service, ping works normally. So I believed something wrong with Squid. But I just change the order of the interfaces, the eth0 now is eth1 and eth1 is eth0 and everything works fine, for now. It seems an issue with the interfaces, exactly don't know. If someone have had this issue with this and has any explication, is welcome. Thanks. I will continue posting my results if someone needs. Have a nice day! 2008/6/6 Henrik Nordstrom <henrik@xxxxxxxxxxxxxxxxxxx>: > On tor, 2008-06-05 at 23:15 -0500, Carlos Alberto Bernat Orozco wrote: > >> I'm new to Squid, so please be patient.
