Description Rok Potocnik 2010-03-26 21:57:21 UTC

Description of problem:
the kernel lacks the ipv6 connection tracking module, statefull firewalling is not possible

Version-Release number of selected component (if applicable):
kernel-2.6.18-164.15.1.el5 

How reproducible:
every time

Steps to Reproduce:
1. ip6tables -I OUTPUT -j ACCEPT
2. ip6tables -I INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
3. ip6tables -A INPUT -j DROP

Actual results:
incoming IPv6 traffic gets dopped

Expected results:
incoming IPv6 traffic should get accepted in case the packet is a direct response of initially outbound IPv6 traffic

Additional info:
even though ip6tables has the correct code (.../iptables/libip6t_state.so) the kernel ignores it whatsoever, the problem is also very noticable in case the server is also a router (e.g. FORWARD table)
