Hi,

   I think that it is possible to achieve some kind of load-balancing 
between two servers using iptables NAPT (Network and port translation, 
which is usually called port forwarding).

I want to run 2 web servers and use my firewall to do some 
load-balancing between them, but I was wondering if it only forwarded 
the packets on some round-robin way, even if one host is down.  To 
summarize, I want to know if I can do some automatic failover with iptables.

If you need more info, let me know

Thanks

Ugo
