Hi, I need help for load balancing my Squid with two ADSL links. I have try to run additional two Squid parent instances on the same machine but with different IPs binded by using tcp_outgoing_address. It works, but sometimes it generate some error on main Squid like this and make the speed going slower than using just one Squid with single ADSL link. 2007/09/19 23:59:16| TCP connection to 192.168.1.254/3128 failed 2007/09/19 23:59:38| TCP connection to 192.168.2.254/3128 failed 2007/09/19 23:59:39| TCP connection to 192.168.2.254/3128 failed 2007/09/20 00:00:21| TCP connection to 192.168.2.254/3128 failed 2007/09/20 00:00:28| TCP connection to 192.168.2.254/3128 failed 2007/09/20 00:00:30| TCP connection to 192.168.2.254/3128 failed 2007/09/20 00:00:31| TCP connection to 192.168.2.254/3128 failed 2007/09/20 00:00:33| TCP connection to 192.168.1.254/3128 failed 2007/09/20 00:00:41| TCP connection to 192.168.1.254/3128 failed 2007/09/20 00:00:42| TCP connection to 192.168.1.254/3128 failed Here is my topology. Main -(round-robin)> Parent1/Parent2 -(tcp_outgoing_address)> ISP1/ISP2 Any idea about this error ?
