This is used to send back an error packet in response to the matched
packet: otherwise it is equivalent to
so it is a terminating TARGET, ending rule traversal.
This target is only valid in the
chains, and user-defined chains which are only called from those
chains. The following option controls the nature of the error packet
\fB\-\-reject\-with\fP \fItype\fP
The type given can be
\fBicmp6\-port\-unreachable\fP or
which return the appropriate ICMPv6 error message (\fBport\-unreach\fP is
the default). Finally, the option
can be used on rules which only match the TCP protocol: this causes a
TCP RST packet to be sent back. This is mainly useful for blocking
.I ident
(113/tcp) probes which frequently occur when sending mail to broken mail
hosts (which won't accept your mail otherwise).
can only be used with kernel versions 2.6.14 or later.
