SlickVPN
SlickVPN’s lack of a Linux client means setup can take a little thought. The website does offer several installation tutorials, though, covering OpenVPN on NetworkManager, Command Line and PPTP setup. They’re more detailed than Buffered VPN, too, though not as easy. The Windows client, which you can run through Wine, works well. It looks good, displays servers in a list or on a map, runs speed tests to find the fastest servers, and has some handy bonus features and settings for more experienced users. Connect directly in Linux and you have access to all the usual OpenVPN tweaks via NetworkManager, or any other OpenVPN-compatible client they want to install. Network novices won’t have as many options, because the SlickVPN website doesn’t offer much help beyond the initial installation.
