[vpn-help] Windows Store App can't open a TCP Socket while using VPN.

[Sörnt Poppe]

Bug report


Problem:

A Windows Console Application works fine, while the Windows Store App 
not. Both programs are working fine when not using a VPN at all.
I contacted the  MS Application Developer Support and send them both 
apps. After some phone calls and Skype message it turns out that both 
programs are running fine within their Test Lab. I installed the 
"Routing and RAS" services at my Windows Home Server, configured the 
port fowarding at the FritzBox and use the MS VPN Client to connect to 
my Network. In that situation both apps are working fine while using a VPN.
It looks like that the Screw Soft VPN Client is not compatible with 
Windows Store Apps.

MS fixed an issues they had with their own VPN Client at Windows 8, it 
got fixed with this Hotfix (http://support.microsoft.com/kb/2797356). At 
Windows 8.1 the hoftix is not necessary.

To reproduce:

Within a Windows Store App: Try open a TCP Socket to a Service which is 
located within the VPN.
Do you need the two mentioned test programs to check that issue?

VPN Client version = 2.2.2. Windows
Windows OS Version = Windows 8.1 64 bit
Gateway make/model = FritzBox 7490
Gateway Software version = 6.05
