DNSMasq? (maybe newer version has it?) For those who uses multiple different devices (especially windows + linux + mac) with Airport Extreme, were you able to get it to do DNSMasq for you? So it'd resolve DHCP names before going to external DNS server?
Nope - sorry. I just had (and returned) my latest one and can confirm it still thinks it has control. The only way I got it to work was to put it behind another router that was running DNSMasq, which sort of defeats the object (unless like me you were planning to use the AEBS purely as an access point). In the end the noise it makes when performing high power transfers was too much for me to bear in my quiet office. If you've a setup like you describe (similar to mine) then you're better off getting a Netgear WNDR3700/3800 and running OpenWRT on it (which is what I'm doing now)
