One IP tunnel may carry thousands of individual PPP 19 connections. L2TP is also used as a VPN protocol, popular 20 with home workers to connect to their offices. 21 22 The kernel component handles only L2TP data packets: a 23 userland daemon handles L2TP the control protocol (tunnel 24 and session setup). One such daemon is OpenL2TP 25 (http://openl2tp.org/). 26 27 If you don't need L2TP, say N. To compile all L2TP code as 28 modules, choose M here. 29
