Hi, I'm using kernel 2.6.19 on Gentoo I have an ipv6 tunnel on the device 'tunbt6', and another interface on eth0 to the rest of my network. I've boiled down my problem to a simple firewall setup. When I enter the following commands: ip6tables -N filter6 ip6tables -A filter6 -m state --state NEW -i ! tunbt6 -j ACCEPT ip6tables -A filter6 -m state --state ESTABLISHED,RELATED -j ACCEPT ip6tables -A filter6 -j REJECT ip6tables -A INPUT -j filter6 ip6tables -A FORWARD -j filter6 It doesn't work! I can't even ping6 the machine over eth0 from my other computer connected to the same ethernet segment! Can anybody tell me what's happening? Thanks
