Dual Wan doing faliover over our website. is it possible?

[kryptos]

Hi All,

I need help for this if this be possible on my setup. We have a website that only our branches can access. Right now we only have one ISP. We have plan to put another Wan(Other ISP provider) now what I want to achieve is to make pfsense to do failover(not loadbalance) on our 2 connections (wan1 and wan2).Is there anything else I should be concerned with like NATing or any other things that I should consider? and if this would be possible?
