-; This is a minimal sample l2tpd configuration file for use
-; with L2TP over IPsec.
-;
-; The idea is to provide an L2TP daemon to which remote Windows L2TP/IPsec
-; clients connect. In this example, the internal (protected) network
-; is 192.168.1.0/24. A special IP range within this network is reserved
-; for the remote clients: 192.168.1.128/25
-; (i.e. 192.168.1.128 ... 192.168.1.254)
-;
-; The listen-addr parameter can be used if you want to bind the L2TP daemon
-; to a specific IP address instead of to all interfaces. For instance,
-; you could bind it to the interface of the internal LAN (e.g. 192.168.1.98
-; in the example below). Yet another IP address (local ip, e.g. 192.168.1.99)
-; will be used by l2tpd as its address on pppX interfaces.

-[global]
-; listen-addr = 192.168.1.98
