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


why not do it for real?

Because, in fact, I'll be using trustix firewall and I know it is based on iptables, and I don't want to do the work if it's already been done.


I'll check lvs if it doesn't do what I want.

Thanks,

-j
