I used to be able to access my Ubiquiti network now with eero Pro I can not...?

my network has the ip address range of 192.168.200.2, etc. but the eero pro gives out the ip address of 192.168.1.1, etc. is there a setting that would allow me to access outside of this ip range? Is it likely a security issue? I never encountered this until installing eeroPro just wondering? Any help would be greatly appreciated. I do need to be able to use network scanner for my business and I need to be able to access these other ip addresses and it was working right up until eeroPro was installed.

I guess not as bad as I was thinking. I put the eero gateway router into bridge mode and that seemed to get it like I wanted so thanks anyway should have thought about that! My bad. Regards.
