I have smartphone clients which are connected to my VPN server. My vpn server is a windows server 2008 implemented az VPN server using RRAS.
Another Windows server 2008 beside the first one, is connected to a vpn server outside the whole network. The network is behind a firewall which prevents normal VPN protocols such as PPTP and L2TP.
The second server is connected to a vpn tunnel server outside the firewalled network through a virtual network interface.
I need 2 windows servers be configured to route smartphone clients' traffic from first server to second server and then through the virtual network interface to the vpn server outside the whole network.
A picture is attached.
Smartphone connects to server 1 using regular vpn protocols. Server 1 routes traffic to server 2. Server 2 is connected to a vpn server outside the network. Server 2 then routes the traffic to tunnel server.
I have configured server 1's RRAS and server 2's tunneling to tunnel server. I just need server 2 to route the traffic through secure tunnel.
