Summary:
Configuring a Dial-Up VPN to Authenticate via WebAuth
Symptoms:
Environment:
  • WebAuth enabled on interface on trust zone
Solution:

Authentication via WebAuth through a VPN allows an extra layer of security for internal resources.

Example:

A remote user needs to make a connection to a server with an internal IP address of 172.16.10.10. To do so, they must first launch their Web browser, and enter the WebAuth IP address of 172.16.10.2. The user will then be prompted for a username and password. After a successful authentication, they should get a Web page with the text 'WebAuth Success'. The user may now communicate with the server.  Below is a sample diagram and key parameters required for configuration.
