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.
Don
You didn't tell us what your v4 endpoint IP was, whether the device is directly connected to internet, etc, please provide enough inormation for us to work with and help you diagnose problem, thanks
