VPN Server

I am looking to setup an IPTV streaming service, whilst it is legally a greyish area within the EU, UK ISP’s are making their best efforts to block these services.

My supplier will accept an IPv6 VPN termination. So my thought’s were to build a VPN server with IPv6 on the public out interface, terminate at my supplier.
& on the in interface, set up PPTP for x clients. With ROS doing the magic across the interfaces

Would this work? What Device would accommodate these requirements.

I was thinking of hosting this in Poland where bandwidth is good and cheap.

Thanks for your comments.
