L2TP (virtual line)

Select this connection type to provide a connection between systems that use Layer Two Tunneling Protocol (L2TP).

Once an L2TP tunnel is established, a virtual PPP connection is made between your iSeries™ server and the remote system. By using L2TP tunneling in conjunction with IP security (IP-SEC), you can send, route, and receive secure data over the Internet.

The L2TP (virtual line) connection type has the following operating modes:

Terminator: Choose this operating mode to enable a remote system to connect to the iSeries server over an L2TP tunnel.
Initiator: Choose this operating mode to enable the iSeries server to connect to a remote system over an L2TP tunnel.
Remote dial: Choose this operating mode to enable the iSeries server to connect to an ISP over a L2TP tunnel, and direct the ISP to dial a remote PPP client.
Multi-hop initiator: Choose this operating mode to enable the iSeries server to establish a multi-hop connection.

Note: The L2TP Terminator profile that this multi-hop initiator is associated with needs to have the "Allow multi-hop connection" box checked and have a PPP validation list entry that links the PPP user name to the multi-hop initiator profile.
