I have 2 network segments 192.168.1.1 and 184.108.40.206 (both of the router IPs).
192.168.1.1 is my home LAN. 192.168.2.1 is my VPN LAN (StrongVPN, if that matters). My iTunes "server" is at 192.168.1.10. My Apple TV is at 192.168.2.100. The VPN router is DD-WRT build 18777. The iTunes "server" is Windows 8 Enterprise.
How do I need to configure my VPN router so that my Apple TV is able to find and stream from my iTunes "server"?
