Hello, We were doing tests with Ip6tables and we noticed a curious event after that rules are created and loaded. After some few minutes, the messages "ICMP NDISC: fake message with non-255 Hop Limit received: 254" are shown in display. If I do "ip6tables -F" after some few seconds this messages are not printed in the screen again. Is there any bug regarding to Neighbor Discovery Protocol and Ip6tables? Thanks and Regards, Marcelo.
