When trying to create certain rules, an invalid error is returned:<br />
<br />
~ # ip6tables -A INPUT -p icmpv6 --icmpv6-type redirect -m hl ! --hl-eq 255 -j DROP -m comment --comment "this is a comment"<br />
ip6tables v1.4.7: Can't specify HL option twice<br />
Try `ip6tables -h' or 'ip6tables --help' for more information.<br />
<br />
The error is invalid because the HL option is not specified twice. Removing the comment from the rule works as expected.
