thanks, bu what i do not understand is the fact, that v6-traffic (even
the responses to http-requests) is completely blocked after successfully
receiving a few echo-replys?
if i modify
${IPT} -A INPUT -i ${INE_IFACE} -m state --state
ESTABLISHED,RELATED -j ACCEPT
${IPT} -A INPUT -i ${INE_IFACE} -p
icmpv6 -j ACCEPT --match limit --limit 10/minute
everthing works fine.
