Configuring an L2TP LNS

An L2TP network server (LNS) is a node that acts as one side of an L2TP tunnel endpoint and is a peer to the LAC. An LNS is the logical termination point of a PPP connection that is being tunneled from the remote system by the LAC. You can configure your E-series router to function as an LNS.
