I have recently purchased a Synology NAS drive and have added it to my network. The NAS drive has the ability to sleep after a specified amount of time with no LAN activity. Unfortunately, the Residential Gateway is constantly chatting and the NAS sees this as LAN activity. Here is my current configuration.
Residential Gateway acts as wireless access point, internet, phone, and tv, an ethernet connection is coming out from the RG into a switch. On the same switch is the NAS drive and an Airport Extreme which is acting as a bridge for USB printing which has a USB printer connected to it.
I have confirmed that the RG is the issue since if I disconnect it from the switch, the NAS drive will go to sleep. I also see less LAN activity as the activity lights on the Airport are no longer flashing.
Any thoughts on the configuration to eliminate the LAN traffic chatting to the NAS preventing it from sleeping? I have connected the NAS to the RG to see if that would make a difference, but it did not. Would setting the RG just as a modem and using the Airport as the access point be a better option?
Thanks for any help,

The U-Verse RG abuses the ARP protocol to maintain its list of connected devices. This is the reason the NAS will not sleep.
The only way to avoid this is to use your own router behind the RG so that the NAS will not be exposed to the RG's broadcast domain.
See the following post for instructions to set up your own router using the DMZPlus feature:

Thanks so much for the information. I will give it a read over tomorrow, probably is pretty complex. I currently have an Airport Extreme that is acting as a bridge for USB printing. Would I be able to use that router for the configuration that you referenced?

I took a closer look at the instructions and thanks for the step-by-step. Have a question though. Is configuring the system this way going to open any security issues for unauthorized connection from the outside world? Looks like the setup is going to use the router as the wireless access point instead of the uVerse Residential Gateway?
Thanks so much for the help,

Thanks. I always struggle with this. Wonderwhich would be the most secure. Normally, it's not as big of a concern, but the NAS will be on all the time.
Thanks again for all your help!
