I'm working on (yet another silly) class paper, where I have to "create" a small five person office environment, as well as give it VPN capabilities. I'm suggesting Debian as the standard distro, but four of the "users" are mobile, and need to be able to connect back to the office remotely. Now, I went over to debian.org, and did a search on VPN clients, but the language therin indicates that the PPTP client is for Microsoft's proprietary technology.
If I'm setting up a pure Linux network, is PPTP the technology I should be using to connect remotely?
