Version 4.1 - 5.10.b SSL VPN
This is a big section with a lot of moving parts. There is a Cisco doc that outlines this technology. The documentation is very long and covers quite a bit. However, the best material for this is actually the INE videos on SSL VPN. The reason I feel they are better than the documentation is that they methodically cover multiple configurations of features.
Entering the webvpn gateway command places the router in SSL VPN gateway configuration mode. The following are accomplished in this task:
•The gateway is configured with an IP address.
•A port number is configured to carry HTTPS traffic (443 is default).
•A hostname is configured for the gateway.
•Crypto encryption and trust points are configured.
•The gateway is configured to redirect HTTP traffic (port 80) over HTTPS.
•The gateway is enabled.
