Also make sure - - you made the default policy for the FORWARD chain in filter table is ACCEPT (for snort inline mode). - to be more wait/sleep few seconds before restarting snort, so that any queued packets gets serviced. or check file /proc/net/netfilter/nfnetlink_queue for queued pkts. Regards, you can write one restart script. steps - remove iptable entries targetting on nf_queue- restart snort- apply iptable entires targetting on nf_queue On Wed, Feb 6, 2013 at 1:56 AM, Andy <a_w_smith () yahoo co uk> wrote: Hi, I am new to snort, I have it installed on a web server running inline mode with iptables, nfqueue, barnyard2 and snorby. I've downloaded the emerging threats rules, firstly all the rules are alerts, do I have to convert these to drop if I want to drop the traffic? Assuming I do, how do I restart snort without loosing good traffic, currently if I kill the process and restart I lose about 30 seconds of traffic while snort restarts, not good on an ecommerce site. I also would like a fail safe nfqueue bypass in case things go wrong, at the moment if snort goes down I also get locked out but its on a cron job to restart if its down for more than 1 minute. I need some advice please..
