New to Pi. I've tried the adafruit tutorial on setting up Pi as a WiFi access point. I can connect from a Windows PC and can ping the Pi (192.168.42.1), but cannot ping the DNS server (22.214.171.124), and of course DNS doesn't work. Tutorial says "something is wrong with dhcpd or the NAT configuration." I've re-checked all the dhcpd and NAT setups but cannot find an error. Ideas on how to debug this further? I'm using the Onion Pi (large antenna) kit.
Any help would be appreciated.
