Access to Devices on Other 3 Ports on Gateway After Adding My Own Router

I am in process of adding my own ASUS router to my AT&T network which acts as the primary of four in a AIMesh configuration.  The primary is plugged into one of the four ports on the AT&T Gateway.  I have a number of other devices, some through switches, plugged into the other 3 ports on the AT&T Gateway.  My question is  once I set up my new router mesh system using the pass-through techniques discussed elsewhere, will I still have the ability to view files across devices still plugged into the AT&T Gateway or do I need to move those other 3 connections to the new Primary Router in my mesh system in order to see them as part of my home network?  I saw an an AT&T message suggesting that after setting up my own router, I may no longer have access to those other devices still using the other 3 AT&T Gateway ports.

Your access to systems and files on those systems connected to the Gateway from clients connected to the Primary Router may be limited, depending on the protocols in use.  Windows SMB networking probably won't work well if at all, Bonjour/mDNS and anything that depends on that will not work, nor anything else that requires a single LAN environment for discovery.  Things like NAS accessed by FTP/SFTP should work fine.

Direct access to system and files on systems behind the Primary Router from clients connected to the Gateway will be non-existent.  There is no way to set up the static route on the Gateway necessary to get the traffic to go through the router plus the router itself wouldn't be configured to pass the traffic.

You would likely be best served to move all your devices to connect through your Primary Router. If you are an AT&T U-verse IPTV customer, then your IPTV equipment is an exception: U-verse TV equipment should all stay connected to the Gateway.
