Setting IP routed subnet (non-NAT) configuration on the RT-AC5300

[Jeff Breidenbach]

I want to do exactly the configuration diagrammed in this article, but for the Asus router. I already have a working NAT, with the router assigned to a static IP address provided by my ISP. Now I want to place some additional computers directly on public internet (no NAT) using additional static IP addresses already assigned by my ISP. My best guess is all the magic happens in Advanced Settings > LAN > Route. Any advice appreciated.
