Configuring Address Assignment
Configuring address assignment applies, and its menus appear, only when you enable at least one
tunneling protocol. If you disabled all protocols, skip to the “Configuring Authentication” section on
page 4-8.
This section lets you configure prioritized methods for assigning IP addresses to clients as a tunnel is
established. The methods are configured, and used, in this order:
• Client specified—the client specifies its own IP address.
