if you want load balancing, you should look at http://www.keepalived.org and/or http://www.linuxvirtualserver.org/ -- Forster Joel Newkirk <netfilter@xxxxxxxxxx>@lists.netfilter.org on 06/14/2003 12:36:55 PM Sent by: netfilter-admin@xxxxxxxxxxxxxxxxxxx To: Jean-Yves Simon <lethalwp@xxxxxxxxxx> cc: netfilter@xxxxxxxxxxxxxxxxxxx Subject: Re: load balancing?

If all you need is to distribute requests evenly across a range of IPs you can use the rule: iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to 10.10.10.1-10.10.10.16 This example would attempt to distribute incoming HTTP requests evenly across the specified range of 16 IPs. j
