You can configure the Asus router for whatever subnet you want so it confirms with the cctv or any other devices addressing requirements. You can also use a dhcp reservation list so static ip's are assigned to the same known devices on the subnet. You can do all of that now as well as set your dns servers etc. The only thing which will change is when you get your hitron the default gateway address will change but the Asus should hand that out to all devices by dhcp anyway.
