NAME

     ppp -- point to point protocol network interface

SYNOPSIS

     options PPP_BSDCOMP
     options PPP_DEFLATE
     options PPP_FILTER

     pseudo-device ppp

DESCRIPTION

     The ppp interface allows serial lines to be used as network interfaces using the Point-to-Point Protocol (PPP).  The ppp interface can use
     various types of compression and has many features over the SLIP protocol used by the sl(4) interface.

     Supported options are:
     options PPP_BSDCOMP   Enable support for BSD-compress (`bsdcomp') compression in ppp.
     options PPP_DEFLATE   Enable support for deflate compression in ppp.
     options PPP_FILTER    This option turns on pcap(3) based filtering for ppp connections.  This option is used by pppd(8) which needs to be
			   compiled with PPP_FILTER defined (the current default).

DIAGNOSTICS

     ppp%d: af%d not supported .  The interface was handed a message with addresses formatted in an unsuitable address family; the packet was
     dropped.

HISTORY

BUGS

     Currently, only the ip(4) and ip6(4) protocols are supported.
