Dear All
I have some problem with applying a state match rules for ipv6 connection=
s.

I=E2=80=99m using a debian unstable with 2.6.16-rc4 kernel.
This is my ipv6 configuration:(/etc/network/interfaces)

auto btexact00
iface btexact00 inet6 v4tunnel
address 2001:618:400:c23b:ffff:ffff:ffff:ffff
netmask 128
gateway fe80::d579:1855
endpoint 213.121.24.85
local 85.88.200.10
ttl 254
ipv6 allocation is 2001:618:400:c23b::/64
for now I=E2=80=99m using only a btexact00 interface for ipv6 output to i=
nternet.
there is also a second interface eth1 for LAN distribution of ipv6 suppor=
t.

It is not long that I=E2=80=99m using a linux ( just about 6 months) so p=
lease
forgive me if I done some stupid configuration.

this is my ip6tables configuration:
cat /etc/iptables.conf/ip6tables-roule.conf

finaly I came to my question:
for some kind of reason the roule:
-A btexact00_in -s ::/0 -d ::/0 -m state --state RELATED,ESTABLISHED -j
ACCEPT
don=E2=80=99t match that king of traffic.
(if i add this roule after the up one : "-A btexact00_in -s ::/0 -d ::/0
-j LOG" log output all the traffic)
I was tray several times to reconfigure all ip6tables supposing that
this was an configuration problem , but the configuration to me seems ok.
Please can you help me?
Best Regards
Undertacker

P.S.
I=E2=80=99m so sorry for my English, I hope you understand this mail.
