rookie setup with Apple airport extreme

[crozierk]

Hi, I'm trying to get a tunnel setup and during the setup part I get the message 'Error: Your IPv4 endpoint is unreachable or unstable. Please make sure ICMP is not blocked. If you are blocking ICMP, please allow 66.220.2.74 through your firewall. ' ..... What the heck is going on i don't see anywhere in the AESB where you can enable or disable ICMP from specific hosts .... I'm on AT&T and using 7.4.2 on the extreme

If you have a modem between the Apple airport  and the internet make sure it is set to return a ping request.
