.SH DESCRIPTION
.I Tncfg
attaches/detaches IPSEC virtual interfaces to/from
physical interfaces,
through which packets will be forwarded once processed by IPSEC.
.PP
The form with no additional arguments lists the contents of
/proc/net/ipsec_tncfg.  The format of /proc/net/ipsec_tncfg is discussed
in ipsec_tncfg(5).
The
.B \-\-attach
form attaches the
.I virtual
interface to the
.I physical
one.
The
.B \-\-detach
form detaches the
.I virtual
interface from whichever physical interface it is attached to.
The
.B \-\-clear
form clears all the
.I virtual
interfaces from whichever physical interfaces they were attached to.
.PP
Virtual interfaces typically have names like
.BR ipsec0 ,
while physical interfaces typically have names like
.B eth0
or
.BR ppp0 .
.SH EXAMPLES
.TP
.B ipsec tncfg \-\-attach \-\-virtual ipsec0 \-\-physical eth0
attaches the
.B ipsec0
virtual device to the
.B eth0
physical device.
