I'm planning to build my first balancer for one of our website, using apaches mod_proxy and mod_proxy_balancer. Having not so many external IP's I'm thinking about to use each machines Internal IP but I can not decide if this would be a good workaround or not!enter image description here

Is it going to be enough fast? This is a usable or not?

This is what everybody else does (who also doesn't have enough IPv4 addresses).

You could also use your IPv6 addresses internally, if you have gotten them yet.

Thank you very much for your feedback. One issue is not really clear for me. How to handle the web contents and mysql database? Is it a problem if the workers are Virtual Machines? – fefe Jan 24 '13 at 8:07
That sounds like a completely different question. :) – Michael Hampton Jan 24 '13 at 8:11
