"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Yes this is a very common setup. Use percent based for the best results IMO

But how does external IP matches to internal IP ? Does it mean I need to setup two NAT rules, two different public IP address (due to 2 different Telco provider) match to same internal IP address ?

Aaron TomoskyDirector of Solutions ConsultingCommented:
Wan load balancing works for external traffic. If you have internal servers like mail or ftp that are accessible from a wan IP, that is harder. The easiest way is to make mail2 and ftp2 for the second connection. Some services like email are easy as you can just add a second mx record.
