Do you have a username and password for PPP? You could replace the device with something with a SPF port
Another option is that you could turn off masquerading (NAT) on the Asus router. This may not work but if you have different IP ranges on each device theoretically it would avoid double NAT

Is the ISP device a cable modem or is it fiber?
You may be able to replace it
