NAME
     l2tpd.conf - L2TPD configuration file

DESCRIPTION
     The  l2tpd.conf  file contains configuration information for l2tpd, the im-
     plementation of l2tp protocol.

     The configuration file is composed of sections and parameters. Each section
     has a given name which will be used when using the configuration FIFO (nor-
     maly /var/run/l2tp-control). See l2tpd.8  for more details.

     The specific given name default will specify parameters applicables for all
     the following sections.

GLOBAL SECTION
     auth file
	    Specify where to find the authentication file used	to  authenticate
	    l2tp tunnels. The default is /usr/local/etc/l2tp/l2tp-secrets.

     Address
	    Specify  which  IP	address l2tpd should use. The default is all ad-
	    dresses.

     Port   Specify which udp port l2tpd should use. The default is 1701.

     access control
	    If set to use, the l2tpd process will only accept  connections  from
	    peers addresses specified in the following sections. CHECK

LNS SECTION
     exclusive
	    If	set  to yes, only one control tunnel will be allowed to be built
	    between 2 peers. CHECK

     (no) ip range
	    Specify the range of ip addresses the LNS will assign  to  the  con-
	    necting  LAC  PPP tunnels. Multiple ranges can be defined. Using the
	    'no' statement disallows the use of that particular  range.   Ranges
	    are defined using the format IP - IP (example: 1.1.1.1 - 1.1.1.10)

     (no) lac
	    Specify  the  ip  addresses of LAC's which are allowed to connect to
	    l2tpd acting as a LNS. The format is the same as the  ip  range  op-
	    tion.

     hidden bit
	    If set to yes, l2tpd will use the AVP hiding feature of L2TP. To get
	    more  information  about  hidden  AVP's and AVP in general, refer to
	    rfc2661 (add URL?)

     local ip
	    Use the following IP as l2tpd's own ip address.

     length bit
	    If set to yes, the length bit present in  the  l2tp  packet  payload
	    will be used.

     (refuse | require) chap
	    Will require or refuse the remote peer to get authenticated via CHAP
	    for the ppp authentication.

     (refuse | require) pap
	    Will  require or refuse the remote peer to get authenticated via PAP
	    for the ppp authentication.

     (refuse | require) authentication
	    Will require or refuse the remote peer to authenticate itself.

     unix authentication
	    If set to yes, /etc/passwd will be used for remote peer ppp  authen-
	    tication.

     hostname
	    Will report this as the l2tpd hostname in negociation.

     ppp debug
	    This will enable the debug for pppd.

     pppoptfile
	    Specify  the path for a file which contains pppd configuration para-
	    meters to be used.

     call rws
	    This option is deprecated and no longer functions.	It  used  to  be
	    used  to  define  the  flow  control window size for individual L2TP
	    calls or sessions.	The L2TP standard (RFC2661)  no  longer  defines
	    flow control or window sizes on calls or sessions.

     tunnel rws
	    This  defines  the	window	size of the control channel.  The window
	    size is defined as the number of outstanding unacknowledged packets,
	    not as a number of bytes.

     flow bits
	    If set to yes, sequence numbers will be included in  the  communica-
	    tion.   The feature to use sequence numbers in sessions is currently
	    broken and does not function.

     challenge
	    If set to yes, use challenge authentication to authenticate peer.

LAC SECTION
     The following are LAC specific configuration flags. Most of those described
     in the LNS section may be used in a LAC context, where it make common sense
     (essentially l2tp procotols tuning flags and authentication /  ppp  related
     ones).

     lns    Set the dns name or ip address of the LNS to connect to.

     redial
	    If	set  to  yes,  l2tpd will attemps to redial if the call get dis-
	    conected.

     redial timeout
	    Wait X seconds before redial. The redial option must be set  to  yes
	    to use this option.

     max redial
	    Will give up redial tries after X attempts.
