Clients using Windows Server 2012's Routing en Remote Access (also client)

I've configured a Windows Server 2012 with RRAS.

The config is:
LanConnection (Host Only) 192.168.101.11
InternetConnection (Shared Network) 10.211.55.19


When I use a Windows 8 client with this server, IP 192.168.101.31
Default gateway en DNS is server IP 192.168.101.11
From the Windows 8 client I can ping the server LanConnection (192.168.101.11).
I can also ping the InternetConnection (10.211.55.19). But I'm unable to ping 10.211.55.1

From the server I'm able to ping 10.211.55.1, also Internet works.

The Windows 8 client has a timeout.

When I change the Shared Network to an adapter, the problem still exists.

Has anyone an idea what I can try to solve this problem?
