@dwinur,

Have you went through the SD-WAN configuration guides and actually read up on how this is configured? That would be the starting point for this, and then you can ask questions if you get stuck on something.

I'm not sure what you mean by the following:

Be mindful that having a device performing NAT in front of the PA can prevent the formation of the tunnels, which means SD-WAN isn't going to work in some cases. You want to try to eliminate that if at all possible during your planning stage.

He wants to NAT his internet traffic going out like you would a single internet connection. So if a single internet connection all internal traffic going out would be configured in the NAT policies as a source NAT Dynamic IP and Port to the outside interface's IP. He wants to know how you do this if your outside interface is an SD-WAN that is combining two different internet circuits each with their own IP on each interface.

On this note, since it had been a minute since I had done it. You specify a NAT policy for each outside interface. So source zone(s) (trust etc) to destination zone (untrust) but specify the physical interface in the middle tab, don't leave it as any interface. Then specify same outside interface in the translated packet tab (Dynamic IP and Port) and that interface's IP.
