How to use TL-WR703N as VPN router
The Apple TV2 doesn't support VPN. One solution is to use a router with VPN support. Our small router bought for less than 20 €, doesn't support OpenVPN, due to its 4 Mbytes flash memory, but supports the PPTP protocol. It is not the best protocol in term of security, but it is faster because of less CPU usage for encryption.
