Hello, I am working on a project dealing with IPv6 and Multicast. I am trying to filter those IPv6 PDUs being sent by my host and containing ICMPv6 Multicast Listener Discovery Protocol (MLDP) PDUs. (In other words I want to see those Multicast Reports which inform a router that my host wants to see those PDUs which are sent to a specific multicast address.)These PDUs shall be queued for some processing within a user space program. I tried a lot of IP6TABLES rules, but just these types of ICMPV6 PDUs are not queued. I tried different rules, but none worked: ip6tables -A OUTPUT -p icmp6 -j QUEUE ip6tables -A OUTPUT -p icmpv6 -j QUEUE ip6tables -A OUTPUT -p ipv6-icmp -j QUEUE I should mention that ICMPv6 HELLO PDUs are well queued. And: ip6tables -A OUTPUT -p ipv6 -j QUEUE The last rule queues all IPv6 PDUs except those I really want to see: MLDP-PDUs. All tests running on Kernels 2.4.18, 2.4.22 and 2.6.0test8 show the same results. Hoping that somebody can help me. Christian Riechmann (riechmann@xxxxxxx)
