PPPX(4)		       FreeBSD Kernel Interfaces Manual		       PPPX(4)

NAME
     pppx, pppac -- PPP	multiplexer device

SYNOPSIS
     pseudo-device pppx

     #include <sys/socket.h>
     #include <sys/ioctl.h>
     #include <net/pipex.h>

DESCRIPTION
     The pppx and pppac	drivers	works with the npppd(8)	daemon to provide net-
     work interfaces for Point-to-Point	Protocol (PPP) sessions	by request
     from the daemon.  pppx operates by	allocating a network interface for
     each PPP session.	pppac concentrates multiple PPP	sessions on a single
     network interface.	 The interfaces	also work with pipex(4)	to accelerate
     the performance of	data packet forwarding,	and supports ioctls which are
     added by pipex(4).

     To	use pppx or pppac from npppd(8)	the administrator needs	to configure
     the interface configuration in npppd.conf(5).  Also the administrator
     needs to enable pipex(4) by setting net.pipex.enable to `1' using
     sysctl(8).

HISTORY
     The pppx driver first appeared in OpenBSD 5.3.  The pppac interface
     driver first appeared in OpenBSD 6.7.
