      "description": "xl2tpd is an implementation of the Layer 2 Tunnelling Protocol (RFC 2661).\nL2TP allows you to tunnel PPP over UDP. Some ISPs use L2TP to tunnel user\nsessions from dial-in servers (modem banks, ADSL DSLAMs) to back-end PPP\nservers. Another important application is Virtual Private Networks where\nthe IPsec protocol is used to secure the L2TP connection (L2TP/IPsec,\nRFC 3193). The L2TP/IPsec protocol is mainly used by Windows and\nMac OS X clients. On Linux, xl2tpd can be used in combination with IPsec\nimplementations such as Openswan.\nExample configuration files for such a setup are included in this RPM.\n\nxl2tpd works by opening a pseudo-tty for communicating with pppd.\nIt runs completely in userspace.\n\nxl2tpd supports IPsec SA Reference tracking to enable overlapping internak\nNAT'ed IP's by different clients (eg all clients connecting from their\nlinksys internal IP 192.168.1.101) as well as multiple clients behind\nthe same NAT router.\n\nxl2tpd supports the pppol2tp kernel mode operations on 2.6.23 or higher,\nor via a patch in contrib for 2.4.x kernels.\n\nXl2tpd is based on the 0.69 L2TP by Jeff McAdams <jeffm@iglou.com>\nIt was de-facto maintained by Jacco de Leeuw <jacco2@dds.nl> in 2002 and 2003.",
