I'm trying to configure my home network so that I can use a drive attached to my airport base station as the Time Machine drive. I think that to do this the Airport needs to control the DHCP and the NAT. I'm not sure I really understand DMZ settings, or if it's possible to push that to a third router...
Current setup includes:
ATT Uverse's 2Wire Modem/Router > Sprint Airave > Apple Airport Extreme.
Everything I've read about this doesn't seem to use three routers. I can connect to the internet, but not able to use Time Machine with my networked drive.
Is Double NAT error that big a deal?
Any thoughts? Any place to read layman's DMZ info? Anyone using a third router as the main DHCP server? Why does everything come with a router? Is my setup just too complicated?
Pre-AiRave, the Airport Base Station was the only thing connected to the ATT 2Wire, and it worked fine. Unfortunately, I sprint says the Airave must be in front of the router. The main concern is to get Time Machine working. That being said, Finder no longer sees the Airport Base station as a 'server' to connect to and simply access the networked drive. Am I barking up the wrong tree?
