Firewall enabled that doesn't allow incoming ICMP echo requests
firewall.cpl ->Advanced-> ICMP-settings. Enable "allow incoming echo requests".

NAT is actually called NAT/basic firewall. It protects the internal LAN from direct access by outside/Internet users. If you want remote users to access the internal network you should be using the RRAS VPN features rather than NAT.

As I understood the question, the problem is that you can't ping the external IP from outside. Is it the only problem?
As I posted earlier, you nead to allow incoming ICMP echo requests for the interface to be able to ping it. I forgot that when using RRAS the normal firewall is replaced by the firewall in RRAS, but you nead to do the same thing in RRAS configuration MMC. Expand the 'IP Routing' and 'NAT/Basic firewall', and click ICMP-tab on the properties dialog for the external interface.
