Do not remove this feature as it is essential for ADSL networks that are using residential gateways (those are using both DHCP internal and external IP adress).
In 1.1.0 everything was working right but in 1.2.0 Beta there is a problem. When i click the "Get IP adress button" it returns me my internal class C ip adress which is useless if i want to use "Direct Connection" since i need the external routable IP.
Now, i need to determine and manually type the external IP in the "External / WAN IP" field, but this is annoying.
