But there were 3 reasons why I wanted to do it with LVS: 1. use more smart schedules than simple random (schedule according to number connections or try make equal network load to all ports). 2. keepalive. LVS knows if service is dead or does not respond and skips route connections to it. 3. connection tracking - statistic how many clients on each port and were they were switched. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
