Xauth Enable | Extended Authentication (XAuth), an extension to the Internet Key |
| Exchange (IKE) protocol. The Xauth extension provides dual authentication |
| for a remote user’s Netopia Gateway to establish a VPN, authorizing net- |
| work access to the user’s central office. IKE establishes the tunnel, and |
| Xauth authenticates the specific remote user's Gateway. Since NAT is sup- |
| ported over the tunnel, the remote user network can have multiple PCs |
| behind the client Gateway accessing the VPN. By using XAuth, network VPN |
| managers can centrally control remote user authentication. |
