-- -- -- xl2tpd is an implementation of the Layer 2 Tunnelling Protocol (RFC 2661), which works by opening a pseudo-tty for communicating with pppd.
L2TP allows you to tunnel PPP over UDP. Some ISPs use L2TP to tunnel user sessions from dial-in servers (modem banks, ADSL DSLAMs) to back-end PPP servers. Another important application is Virtual Private Networks where the IPsec protocol is used to secure the L2TP connection (L2TP/IPsec, RFC 3193). -- -- -- Tested running as a LAC (l2tp client) with aaisp.net.uk; it's not perfect yet but gets the job done. We don't have anything else in-tree to carry out this particular function (npppd only handles LNS, i.e. server side). OK to import?
