Win2003 RRAS port forwarding does not work...

I set up a small lab using VMWARE
To islolate this lab, I am using a Win2003 Std as RRAS with 2 NIC cards:
internal (LAN of my LAB - 10.10.10.0)
external (to the Internet, to my router)
RRAS is not a member of the internal domain

It works fine for clients behind this server, I can access the Internet, RRAS is working.

But port forwarding does not work. I setup a rule on RRAS under external NIC card to forward 8888 to 3389 to a local PC of 10.10.10.1
Does not work

What I checked:
- I can access this RRAS from outside (ping, RDP)
- netstat -ano does not show any 8888 as a listening port (?)
- full connectivity between RRAS and 10.10.10.x
- 10.10.10.1 is accessible using RDP from internal network

I found somewhere, that that it might be sth like this:
sounds like a loopback adapter problem. Does your RRAS device have a DNS server? If it does, add your domain name as an entry with both the external IP address of your network, and the internal IP address of your server. That should fix the problem. Else, you may have to do the host file hack.

And it sounds familiar as on this RRAS server I point to my AD DNS... But how is it related???

Any ideas?
