NOTE CSTP is a Cisco proprietary protocol for SSL VPN tunneling. “In” represents that the packet comes from the client. “Out” represents that the packet is sent to the client. The client is the PC running the Cisco AnyConnect Secure Mobility Client software that connects to the security appliance running the SSL VPN server. A CSTP frame is a packet carrying the CSTP protocol information. There are two major frame types, control frames and data frames. Control frames implement control functions within the protocol. Data frames carry the client data, such as the tunneled payload.
