Anyone have global inside ip ping issues when nat outside is applied ?

Hi there

recently went from an ADSL internet service to an IPVPN internet service.

Having issues with pinging the global ip provided by the new ISP WHEN “ip nat outside” is applied to the outside interface on my 2811 router.

When i dont attempt to do translation of inside lan ips to the inside global ip ie there is no “ip nat outside” on the outside interface i can ping the golbal inside ip from the routers cli and from the internet.

Once i apply “ip nat outside” i cant ping the ip from the routers CLI or see it from the internet. However my lan ips can access the internet just fine.

put simply, whenever nat is applied the router cant ping its own global ip on the outside interface.

anyone have similar problems ? .
