Event ID 17 — RRAS Secure Socket Tunneling Protocol

Applies To: Windows Server 2008 R2

Secure Socket Tunneling Protocol (SSTP) is a new form of virtual private networking (VPN) tunnel with features that allow traffic to pass through firewalls that block PPTP and L2TP/IPsec traffic. SSTP provides a mechanism to encapsulate Point-to-Point (PPP) traffic over the Secure Sockets Layer (SSL) channel of the HTTPS protocol. The use of HTTPS means traffic will flow through TCP port 443, a port commonly used for Web access.
