I am setting up a new eero Pro 6E on BellAliant Fibe in Canada and am not having much success.

First, I tried connecting to my Fibe modem via double-NAT and doing this, the router is able to connect to the internet.  If I read this article correctly, this is something that should work.

However, I connected both an iPad and an iPhone to the eero via Wifi and although they get a valid IP and can be seen as connected on the eero app, neither were able to access the internet.

After some research on the community forum, I found the following:

The potential third option is to look for a feature called "Advanced DMZ" or some such. Again, I'm not a CenturyLink customer, but I've read several reports that this is a possibility on at least some of their routers, and it's what I'm using with my ISP (Bell Fibe in Canada). The "Advanced DMZ" feature lets the router actually assign the *public* IP address to the Eero, at which point it acts just like the C1000A isn't in the loop at all.

So I setup Advanced DMZ on my modem for the eero.  The modem shows the eero as being properly connected and having been assigned a public IP address.  However, after doing this and rebooting the eero, it’s light is red as is unable to connect to the internet.

From what I can see in the modem settings, and because I use it to also use it for phone and TV services, I do not believe that I can set it to Bridge mode.  (There is no options for this in its settings either unfortunately.)

Is there anything else that I could try to get the device working?  Has anyone else had a similar issue, and if so, were you able to resolve this?

Thanks in advance!
