    Good stuff, thanks. Same situation, only ISPs (Gi1 and Gi2 in your diagram) are each in a different VRF - Internet1 and Internet2. I've tried the config you demonstrated but it doesn't work, presumably because of the VRFs. (Gi0 / Inside is GRT). When I use a basic NAT statement as in a single ISP (no route-map), it works, but of course I must change the nat manually or use EEM triggered by IP SLA tracked object. So, what am I missing? Will this even work with VRF's? I have seen similar NAT use cases where it simply won't work when overloading an interface, must be a different IP - is this one of those cases? TIA!

      Hi Gary, interesting scenario. Now rather then asking you a bunch of questions, I would request if you could send the running config of your router to info@doctornetworks.net. I will be happy to assist (No charges).

    What if we configure Two ACLs with different names like INTERNET & INTERNET2 and then call them into two different statements of NAT, would that work?

      If the outgoing Interface's are different it will definitely work, If the interface's are same, it will replace it with the latest nat statement you type.

    Hello, is there a way to have NATed traffic being balanced?

      On cisco NO. You can do that on Fortigate by utilising the SDWan feature

      PBR/PFR. Not truly balanced, that's impossible with two different ISPs, but you can direct traffic x on int1 and traffic y to int2. In route- map you set next hop based on your traffic matching.
