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