First of all, I installed 2 network adapters. It can be done with only one, but with upcoming changes in April I guess I'm going to need two 

The first has IP 10.0.0.1, but can be any within this range.
The second I gave IP 10.166.193.217, according to the internal IP from my ISP using VPN. DO NOT USE YOUR REAL EXTERNAL IP!!!
Set E-smith up without dial-up. Otherwise your ADSL settings will not be saved.
Download ADSL4Linux from 
http://www.adsl4linux.nl/ and save it to your server. Install and set up the program. This is very easy with user interface. The installation save all settings.
Type adsllogin to make connection and adsllogout to break the connection.
WHY did I gave the second network adapter the internal IP from my ISP? When you use your real external IP, e-smith cannot detect any incoming connection. Ok, that is very safe, but you cannot run it as a server
