Loopback Configurations

[LPJC]

Ok here is my Question:

Once i have configured my FW rule and and Nat Policy for example a web that can be accessed from the internet. but i want to test the rule from with in the LAN (hence the suject called loopback). I open IE/Firefox on a LAN machine and enter in the external Nat IP of the Webserver and page can no tbe displayed, but it does work if your a WAN source conencting to the webserver.

So what config or rules do i need to put in place in order to perfrom loopback tests etc…

Thanks
