I’m trying to get ip6tables to work in my SLES10 SP2 box with kernel 2.6.16.60-0.42.5-smp. It does work when adding simple rules like, allowing all icmpv6 traffic, but whereas I’ve had no problems with SLES11 SP1 2.6.32.49-0.3 and SLES9 SP3 2.6.5-7.318, the SLES10 box does not behave as expected with related packets. After Googling for a while, I think the reason why ip6tables is not working properly, is because the module nf_conntrack_ipv6, which I have found in the SLES11 and SLES9 boxes, is not present in the /lib/modules/uname -r/kernel/net/ipv6/netfilter directory in the SLES10 box.
Has anyone had the same problem? Is anybody runnning ip6tables in SLES10 SPX with no problem?
