Hi, I tried to filter IP packets with ip6tables (next hdr field) But as you can see in output [1] the kernel maps "0" to all and not to ip as listed in /etc/protocols. With default policy DROP this might not that big problem in dual stack mode, but in case I want to check if IPv6 with IPv4 encapsulated arrives, I have no chance to LOG Am I running in the wrong direction (an the kernel drops these packets silently or forwards them to ipv4 netfilter hooks) or is this an implementation error that might need to be fixed? Thanks for your great iptables/ip6tables support best Bernd [1] http://pastebin.com/jC4rwpG4 -- UMIC - RWTH Aachen http://www.umic.rwth-aachen.de Mies-van-der-Rohe Str. 15 52074 Aachen Tel.: +49 241 80 20791 Fax: +49 241 80 22731 E-Mail: kohler@xxxxxxxxxxxxxxxxxxx RIP Dennis Ritchie (*09.09.1941 †09.10.2011) Thx 4 UNIX and all the ><(((('>
