I have placed the code below right underneath the route portion in the kamailio.cfg file restarted kamailio and I am still being attacked.

####### Routing Logic ########


# main request routing logic

route{

        if ($ua=="friendly-scanner") {
                sl_send_reply("200","OK"); 
                exit;
        }

>>>> it is comming from "friendly-scanner" The other issue I have is that "/var/log/secure" is not getting the sip requests so the only way I realize it is happeing is from tcpdump.  If the secure file is not picking it up then iptables wont know about it.  How can I tell iptables to listen for sip requests?  I have already added the IP to the blocked IP's but he still keeps on comming.

If I look at "/var/log/secure" there are no SIP messages.  My question is where is the log file for Kamailio and how can I prevent this type of attacks in the future.
