I have 2 servers hosted in the cloud. One an application server, one a VPN server, both running Win2008.
Both have a local IP address assigned by DHCP in different network subnets, 10.227.55.0 (VPN) and 10.231.5.0 (App Server). These servers can ping each other.
My VPN client connects in to the VPN server (using a L2TP connection on a Win7 client). It is assigned an IP Address from the VPN server's static pool (the VPN server takes 192.168.100.1, the client is given 192.168.100.2). The client can ping both the 192.168.100.1 address of the VPN server, and its 'local' IP address (10.227.55.X).
What the client can't do is ping the App Server. How can I configure routing so that my client can access the App Server, without hard-coding any of the DHCP IP addresses anywhere?
