VPN - LogmeinHamachi Open VPN Windows VPN

I have a Windows 2012 Server that is running some reporting software set up as a sandbox.  I will have multiple colleagues accessing this server for the purposes of doing demos etc.

I am looking for a VPN Solution (I am prepared to pay as performance and reliability are very important) and evaluating the pro's and con's of:

I) LogMeInHamachi
II) OpenVPN
III) Windows VPN

The reliability - stability of the VPN connection and the performance (speed) are very very important to me.  Security is of course something I would like to be relatively robust.

Please provide good details (some posts on EE simply refer to a URL and I have already done a good deal of research - looking for expertise here).

Thanks!

OpenVPN: Reliable, secure, speed depends on encryption algorithm chosen (default is Blowfish, which is good). Needs OpenVPN software and certificates (which can be generated easily with the tools provided). Can be used for on-demand or always-on connections without restrictions.

Windows VPN: Usually is PPTP, and security is an issue. The encrpytion depends on the password chosen, and PPTP is considered to be unsafe for always-on connections, but ok for occasional dial-in. Reliability is an issue if crossing NAT routers with the same (public) source and destination addresses.

In any case, you will use RDP sessions. Having data connections over VPN and expecting good performance is contradictory.

Hi Qlemo,

Many thanks for detailed response!

Well, let me explain why we are using VPN.   We have a reporting software (SAP) that is installed on local machines / devices.  We want to connect to the sandbox where the reporting server resides to run reports.  The local software installed on the 'client' device will connect to the server via VPN to run reports (this is how companies normally do it) - the data itself is stored and run on the server and the reports are passed to the device so there will be some reasonable volumes of data going across but most of the heavy lifting done by the server.  This is all standard practice btw.

Can you advise what type of performance can be expected with Open VPN?

No, I can't tell. The experience is depending on the circumstances.
Note that applications like SAP is almost always used in Terminal Server sessions if remote - for very good reasons. However, a "single request" scenario might be ok, like reporting might be.

In the end you will have to try. Since both OpenVPN and PPTP are software-encrypted VPNs, you can't give any estimates about performance.
