1. Does anyone know, or know of a good explanation of, how to set up a L2TP VPN based on a Windows Server 2003 machine? I'm tired of dicking around with little metal boxes running proprietary OSes that are impossible to configure without a special training class offered by the manufacturer. 2. Why do IPSEC VPNs cost money per user, while SSL VPNs are free? What's so special about IPSEC that every VPN manufacturer charges extra for user licenses, on top of the cost of the box itself?
