1 This is used to send back an error packet in response to the matched
2 packet: otherwise it is equivalent to
4 so it is a terminating TARGET, ending rule traversal.
5 This target is only valid in the
10 chains, and user-defined chains which are only called from those
11 chains. The following option controls the nature of the error packet
14 \fB\-\-reject\-with\fP \fItype\fP
16 \fBicmp6\-no\-route\fP,
18 \fBicmp6\-adm\-prohibited\fP,
19 \fBadm\-prohibited\fP,
20 \fBicmp6\-addr\-unreachable\fP,
22 \fBicmp6\-port\-unreachable\fP or
24 which return the appropriate ICMPv6 error message (\fBport\-unreach\fP is
25 the default). Finally, the option
27 can be used on rules which only match the TCP protocol: this causes a
28 TCP RST packet to be sent back. This is mainly useful for blocking
30 (113/tcp) probes which frequently occur when sending mail to broken mail
31 hosts (which won't accept your mail otherwise).
33 can only be used with kernel versions 2.6.14 or later.
