ip6tables adds wrong address when entering src/dst as ff::/8

Hi All,

For my filtering rules, I'm trying to add the following:

ip6tables -t mangle -I AuthCheck 1 -d ff::/8 -j RETURN ip6tables -t mangle -I AuthCheck 1 -d fc::/7 -j RETURN

However, when I check the rule entries they show up as:

1 0 0 RETURN all * * ::/0 ::/7
2 0 0 RETURN all * * ::/0 ::/8

Which obviously doesn't catch the packets as ::/7 or ::/8 is not fc::/7 or ff::/8

This is with ip6tables version:

ip6tables v1.4.15

Does anyone else get the same problem?

You need to give it as fc00::/7 not fc::/7
