Abbreviation for Lines, "#LNS" is the number of lines

L2TP network server. A termination point for L2TP tunnels, and an access point where PPP frames are processed and passed to higher-layer protocols. An LNS can operate on any platform that terminates PPP. The LNS handles the server side of the L2TP protocol. L2TP relies only on the single medium over which L2TP tunnels arrive. The LNS initiates outgoing calls and receives incoming calls. An LNS is analogous to a home gateway in L2F technology.

L2TP Network Server. An LNS operates on any platform capable of PPP termination. The LNS handles the server side of the L2TP protocol. Since L2TP relies only on the single media over which L2TP tunnels arrive, the LNS may have only a single LAN or WAN interface, yet still be able to terminate calls arriving at any LAC's full range of PPP interfaces (async, synchronous ISDN, V.120, etc.).

L2TP Network Server PPPoE

L2TP network server. A device that terminates an L2TP tunnel. It receives the remote user PPP connection over an L2TP tunnel. The LNS authenticates and authorizes the remote user and then forwards packets between the remote user and the data network.

L2TP network server. A node that acts as one side of an L2TP tunnel endpoint and is a peer to the L2TP access concentrator (LAC). The LNS is the logical termination point of a PPP session that is being tunneled from the remote system by the LAC. Analogous to the Layer 2 Forwarding (L2F) home gateway (HGW).

L2TP Network Server. A router that resides at the corporate network and serves as the termination point for L2TP tunnels and sessions. See also LAC, VPN.
