1This is used to modify the Hop Limit field in IPv6 header. The Hop Limit field 2is similar to what is known as TTL value in IPv4. Setting or incrementing the 3Hop Limit field can potentially be very dangerous, so it should be avoided at 4any cost. This target is only valid in 5.B mangle 6table. 7.PP 8.B Don't ever set or increment the value on packets that leave your local network! 9.TP 10\fB\-\-hl\-set\fP \fIvalue\fP 11Set the Hop Limit to `value'. 12.TP 13\fB\-\-hl\-dec\fP \fIvalue\fP 14Decrement the Hop Limit `value' times. 15.TP 16\fB\-\-hl\-inc\fP \fIvalue\fP 17Increment the Hop Limit `value' times. 18
