Is your sensor inline? You can test to see if the rule will drop by running snort something like this: ./bin/snort -c etc/test.conf -Q --daq dump --daq-var load-mode=read-file -r etc/test.pcap -l. -H -U -k none -q The daq will dump an inline-out.pcap that you can look at and see the reset packets in there. I just tested this on a rule and it works.

Those machines should not allowed to access specified urls. I would like to achieve this using pf_ring without any packet loss. 09/28-14:23:45.058089 [Drop] [**] [1:200001:1] Facebook is Blocked [**] [Priority: 1] i am getting this alert on the server machine but the client could access the website. Previously, i could achieve this using daq -nfq module. Thanks,
