As specified in this earlier blog post, we are dropping L2TP in favor of PPTP due to it’s support and responsiveness.
We are reconfiguring our L2TP server to PPTP connection for support for mobile devices. As such over the next 48 hours there will be some intermittent connectivity with L2TP and US Surfing Streaming as the server is brought down for reinstall and reconfiguration. The US-SurfingStreaming service lies on the same server and therefore will also experience the same intermittent connectivity.
Despite the vulnerabilities of PPTP VPN connections, L2TP seems to be problematic with many mobile devices and PPTP remains the most widely supported VPN protocol in devices. As most users use it primarily to appear from a different location rather than hardcore security, we feel this is an acceptable solution for the intended users of the L2TP server. In any case, it would make the occasional Firesheep/Facebook hacker on a public wi-fi think twice before attempting to break the PPTP VPN. PPTP also has low overhead making it a more responsive protocol.
And so, we have uploaded a PPTP VPN guide, following the change from the L2TP VPN option. You will have to enable encryption during setup as shown in the guide.
For your information (in case it is unclear), the server is located in the United States.
