AFAICT, iptables and ip6tables operate on two separate tables, one for ipv4 and one for ipv6? Certainly, when I list the tables, the contents are different. It seems to me that 'iptables' ought to work with both of these formats: iptables -A INPUT -p tcp -s 192.168.77.77 -j DROP iptables -A INPUT -p tcp -s ::ffff:192.168.77.77 -j DROP The latter format is not recognised by iptables. Nor surprisingly though, it works with ip6tables: ip6tables -A INPUT -p tcp -s ::ffff:192.168.77.77 -j DROP The real question is - will the latter actually drop IPv4 traffic from 192.168.77.77 ? -- Per Jessen, Zürich (9.3°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
