I see this tutorial, http://djinnsour.com/2015/08/23/adding-a-public-ip-address-to-a-system-behind-pfsense-using-nat-11/. Author of this blog say, add external ip to this network, so what is the public ip ( whatismyip ) of that machine?

Referring to that tutorial, the external IP address (routable) would be the 222.222.222.x range address.

Anything within 192.168.x.x will be a private range which can only be used internally as per RFC1918 hence why you would use NAT.

Hope this helps you on your quest.

    That is a valid public IP but obviously it is only an example. This particular IP range is belongs to China and has been assigned to China Telecom hebei. – SleepyMan Aug 17 '16 at 13:02
  • Yes they should have use an IP from rfc5737 but not everybody is aware of this, it's common to pick any IP as example rather than the official documentation IPs. – JFL Sep 16 '16 at 10:24
