Using Deco Mesh with ONT, connecting Sky router as secondary off the Deco - would it even work?

[ChrisGreen]

Full Fibre install happening tomorrow, and I've just been thinking (partly as nobody has been able to reply to my other post asking about how to configure the Sky Router to minimise double nat issues with my mesh).

I need the Sky router as I need the landline. However, rather than have the Sky router connect directly to the ONT, could I connect my Deco mesh directly to the ONT and then daisy chain the Sky router off of that (rather than the other way around)? That way only things connected to the sky router would experience doube nat (which will only be the phone). I have no idea if this would even work, but hoping someone will know (and maybe has even tried it).

Thanks

No-one has reported that this configuration works for Sky Talk Internet Calls.  I suspect the Sky Hub has to be the primary router for telephony to function.

@TimmyBGood Suspected that might be the case, but figured it was worth exploring as an option.
