I have a Windows 2008 R2 server in one location, MS RDS role, for our client's access.
I have a few different clients from varying companies who are Firewalled blocked outbound from using port 3389. Uphill battle getting the IT security policy modified. We can assume these clients are all on Windows 7 Pro PCs or newer.
Can I use VPN to solve this? Or alternatives?
What's the easiest way to setup VPN for this? I only need 3389 to our one RDS server. Our clients are at different companies. Do we need a 3rd party involved such as Hamachi ? And/or set up something with our Cisco 5505 router?
