Don't understand DNAT

StoneCut
Hi !

I'm new here, please be patient with me   

I was looking at the NAT features in ASL and while Masquerading makes perfect sense I was thinking how I could make the DNAT work.

Scenario: My external interface on ASL has 63.63.63.63 and I would like to forward all HTTP Traffic to a webserver running on 192.168.1.2.

Now, if I choose DNAT I can choose a service type (HTTP), then I select internal address but then I can't type in the IP and/or port of my web server but instead I'm am given a list of services to choose from again. Where do I enter the computer I want to forward to ? Please excuse me if this is a really lame question but I'm truly puzzled.

Many thanks for your help !

    You have to first define the computer in Network Definitions.

    It will then appear in the SNAT/DNAT dialog.

    So create a rule similar to....

    All Port 80 traffic to ExternalInterface, forward to ComputerUDefined.  Do not change source or ports.
