[Snort-users] Newbie question: reject rule for IPv6

I am using following command to start snort.
snort -c /etc/snort.conf -N -D
Also I have set following parameters in snort.conf.
config daq: nfq
config daq_mode: inline
config daq_var: proto=ip6
Note that I have built both daq and snort with --ipv6-enabled option.
-A INPUT -d <ip_address>/128 -p tcp -m tcp --dport 80 -j NFQUEUE --queue-num 0
The setup works fine as I am seeing alerts getting logged when I send
a http request with URI contains "snort-test", but unfortunately the
request is not getting rejected ( No ICMP6 unreachable ) as it
should've been and request is going through.
In fact I tried 'drop' too , without any success. Can someone point
out the code where ICMP unreachable is sent ? I tried to debug daq and
always verdict to NFQUEUE is set as NF_ACCEPT.
Thanks for the response.
