Package xl2tpd

Layer 2 Tunnelling Protocol Daemon (RFC 2661)


xl2tpd is an implementation of the Layer 2 Tunnelling Protocol (RFC 2661).
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). The L2TP/IPsec protocol is mainly used by Windows and
Mac OS X clients. On Linux, xl2tpd can be used in combination with IPsec
implementations such as Openswan.
Example configuration files for such a setup are included in this RPM.

xl2tpd works by opening a pseudo-tty for communicating with pppd.
It runs completely in userspace.

xl2tpd supports IPsec SA Reference tracking to enable overlapping internak
NAT'ed IP's by different clients (eg all clients connecting from their
linksys internal IP as well as multiple clients behind
the same NAT router.

xl2tpd supports the pppol2tp kernel mode operations on 2.6.23 or higher,
or via a patch in contrib for 2.4.x kernels.

Xl2tpd is based on the 0.69 L2TP by Jeff McAdams jeffm@iglou.com
It was de-facto maintained by Jacco de Leeuw jacco2@dds.nl in 2002 and 2003.
