Arris 3450 with Orbi RBK50 - DMZ Setup
Last week I purchased an Orbi RBK50 and had no problems. Today I was given a new Arris 3450 Modem/Router by my cable company. This is the first modem/router I have had and wasn't expecting it. So ...
192.168.0.2 is the IP that the Orbi is getting, I made it static. I ended up taking the / out of the last "octet" of he IPv6 and leaving it and all the others 0. It saved and seems to work, so I hope I am good now.

This is the first modem/router I have had and wasn't expecting it. So I looked up the best way to set it up and before even connecting it I logged in and enabled bridge mode. Once I did that I could not get back into the 3450. I ended up resetting the 3450 so I could log back in. The second time I connected the cable to it and logged in and enabled bridge mode again. After rebooting I got the same result, could not connect to the router but the light did turn green indicating it had internet. So I reset it one more time.
Now with the Orbi still in router mode I connected it to the 3450 but I don't want this double NAT setup. So this time I tried configuring the DMZ on the 3450 but it is requiring an IPv6 address in addition to the IPv4 before it will let me save. I have looked and can't figure out what IPv6 address the Orbi is getting. I have played with the IPv6 on the Orbi but don't see any IPv6 address listed for it.
The Arris 3450 has 2604:5c80:201:46a0 prefilled but I don't see anything that start with this anywhere. Any help on the best way to configure this would be appreciated.
you're going to be in a dougle NAT setup as long as you have the modem they gave you.
maybe this will help:

Right, but I would like to use the Orbi as the router and not an access point which is why I was trying to setup the DMZ.
