PPPX(4)                  BSD Kernel Interfaces Manual                  PPPX(4)

NAME
     pppx -- PPP multiplexer device

SYNOPSIS
     pseudo-device pppx

     #include <&lt;sys/socket.h>&gt;
     #include <&lt;sys/ioctl.h>&gt;
     #include <&lt;net/pipex.h>&gt;

DESCRIPTION
     The pppx driver works with the npppd(8) daemon, allocating a network
     interface for each Point-to-Point Protocol (PPP) session by request from
     the daemon.  It also works with pipex(4) to accelerate the performance of
     packet forwarding and supports ioctls which are added by pipex(4).

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

SEE ALSO
     inet(4), inet6(4), pipex(4), hostname.if(5), npppd.conf(5), netstart(8),
     npppd(8), sysctl(8)

HISTORY
     The pppx driver first appeared in OpenBSD 5.3.
