"IP is not ICMP pingable. Please make sure ICMP is not blocked. If you are blocking ICMP, please allow 66.220.2.74 through your firewall."
I get this error when I'm trying to Create a new tunnel.
So, I configured my firewall to allow ICMP but still not working.
Then I completely disabled my firewall and tried again but still got no response.
What shall I do ? :'( :'( :'(
Is your isp blocking it?
Is your isp doing carrier grade nat so you have a private ip address?
I don't know about the fact whether my ISP is blocking it or not.
There is a NAT option enabled on my router WAN settings page.

That NAT setting would probably be for your internal addresses.
Is your public IP in one of the RFC1918 ranges?
