npppd —
new Point-to-Point Protocol daemon
npppd |
[-dn] [-f
config_file] |
npppd is a Point-to-Point Protocol (PPP) and tunneling
daemon capable of L2TP, PPTP, and PPPoE.
-d- Do not daemonize. If this option is specified,
npppd will run in the foreground and log to
stderr.
-f
config_file- Specify an alternative configuration file.
-n- Configtest mode. Only check the configuration file for validity.
Normally npppd works with
pipex(4) to accelerate IP packet
forwarding, but pipex(4) is disabled by
default. To enable it, set net.pipex.enable to
‘1’ using sysctl(8).
When npppd uses PPTP, the host system
should allow GRE packets, but they are disabled by default. To enable GRE,
set net.inet.gre.allow to ‘1’ using
sysctl(8).

The npppd program first appeared in
OpenBSD 5.3.
The npppd program was written by Internet Initiative
Japan Inc.
If l2tp-require-ipsec is set to “yes” with
an L2TP tunnel, all incoming L2TP/IPsec packets are dropped.
