WebVPN (or often called SSL VPN) (or sometimes called clientless VPN) is used when someone needs to access a web based application that is on the private network. A web browser is used for all the encryption and authentication.
After applying the config below the web user should be able to point their browser to https://188.8.131.52 to access the device at 192.168.11.2.
First make sure to have a SSL certificate on the ASA. This is needed because the ASA is acting as a web proxy and requires an SSL cert to be there to create the connection to the client.
Configure the WebVPN
Once the Group Policy and Tunnel Group are created go into ASDM to control the look and control what websites the user can access.
