Concentrator Remote Access Connections with PPTP, L2TP, and WebVPN

The last chapter introduced how to configure the VPN 3000 concentrators to accept IPsec remote access sessions. This chapter will focus on using a concentrator to terminate other types of remote access sessions, including:

• PPTP
• L2TP over IPsec
• WebVPN

The remainder of this chapter will focus on the configuration of the concentrator to support these types of remote access VPN implementations. I'll spend more time on implementing PPTP/L2TP connectivity in Chapter 13, "Windows Software Client." Most of this chapter is dedicated to the newest CiscoVPN implementation: SSL. Cisco refers to their SSL VPN implementation as WebVPN. I'll focus on setting up the concentrator to accept clientless connections (just a web browser), thin client connections (port forwarding), and network client connections (SSL VPN Client software).
