Hello, First of all, excuse me for this off topic subject. I want to set up a VPN with Windows Clients. I want it: - encrypted (of course) - key authentificated - Open Source - cheap I have tried PoPToP but it doesn't support key authentification. Do you know any good software ? The client PCs are running Windows NT/98/2000. -- Best regards, Jean-Francois mailto:jfjoly@free.fr
