1 This module matches IPv6 extension headers and/or upper layer header. 2 .TP 3 \fB\-\-soft\fP 4 Matches if the packet includes \fBany\fP of the headers specified with 5 \fB\-\-header\fP. 6 .TP 7 [\fB!\fP] \fB\-\-header\fP \fIheader\fP[\fB,\fP\fIheader\fP...] 8 Matches the packet which EXACTLY includes all specified headers. The headers 9 encapsulated with ESP header are out of scope. 10 Possible \fIheader\fP types can be: 11 .TP 12 \fBhop\fP|\fBhop\-by\-hop\fP 13 Hop-by-Hop Options header 14 .TP 15 \fBdst\fP 16 Destination Options header 17 .TP 18 \fBroute\fP 19 Routing header 20 .TP 21 \fBfrag\fP 22 Fragment header 23 .TP 24 \fBauth\fP 25 Authentication header 26 .TP 27 \fBesp\fP 28 Encapsulating Security Payload header 29 .TP 30 \fBnone\fP 31 No Next header which matches 59 in the 'Next Header field' of IPv6 header or 32 any IPv6 extension headers 33 .TP 34 \fBproto\fP 35 which matches any upper layer protocol header. A protocol name from 36 /etc/protocols and numeric value also allowed. The number 255 is equivalent to 37 \fBproto\fP. 38
