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.
