ip6tables problem

[Asfand Yar Qazi]

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
