HD300 & Server: Communicate across different subnets

[skyeclad]

Hey gang, I need some advice.

I'm in a FIOS home and use the FIOS modem/router as well as a second router. I used to have the second router in Access point mode and connected to the first router via MOCA on the same subnet. All devices were happy to be able to see each other BUT all of the fancy features(QOS, Parental controls, etc.) of the new ASUS RT-AC5300 were turned off and I need some of those features.

So I switched the ASUS router back to router mode and plugged the FIOS router into the WAN port. The ASUS router decided to create a second subnet and all seemed to be fine except for one thing. My SageTV Server and Extenders are on 2 different subnets.

The question that I have is, should I try to get the devices talking across subnets(if that's even possible) as communication at this point seems like it's only working in one direction.

OR

Should I just buy wireless bridges for the HD300's and have them connect to the server's network?
