I'm a new FTTN Sonic customer. I have the 5268ac, which we must use, but I want to keep using my Asus RT-AC3200 wireless router. I am plugging my ASUS router's WAN port into one of the LAN ports on the 5268ac and disabling the 5268ac's wireless. I am realizing that there are a couple of ways to do this.

My initial testing shows that when I set up the AC3200 as a DMZ, the AC3200 WAN IP address is passed through from the 5268ac. When I set up my AC3200 as a cascaded router, it assigns a private ip address to the AC3200 WAN port as it would any other client. I kept the default private network on the 5268ac as 192.168.1.0 and my AC3200 was set to use 192.168.2.0 for its LAN side.

My question is; Is it better to configure the 5268ac to see my other router as a cascaded router or setup my AC3200 as a DMZ device? What does setting it as a cascaded router actually do? Lastly, did I capture the only possibilities?

Thank you in advance for any feedback.
