Hello.
I was wondering if someone could help me here. From time to time I stat to receive from the internet this SIP message :

The only way that I have now for blocking this packet to hit the Kamailio server is via iptables :
iptables -A INPUT -s 190.22.140.170 -p udp --dport 5060 --jump REJECT
Is there a better way to do this?!
Thanks in advance,

IMHO preventing the packet to reach kamailio is better (via iptables) than doing something in kamailio itself....

Hi,
Do you have any client that is sending a corrupt request to the "AddPac SIP Gateway" at 190.22.140.170, so that this gateway is replying "400 bad request" ? Maybe you could resolve this problem at the source..
If it's not the case, you can send an email to the owner of the IP address. A quick lookup on the IP address on www.network-tools.com gives you a hint on the owner.

Hello,
I see the message gets to the config file, hitting sanity module. What you can do is to use fail2ban for automatic interaction with iptables -- you can inspire from this tutorial:
* http://kb.asipto.com/kamailio:usage:k31-sip-scanning-attack#fail2ban
You will just have a different condition, based on sanity and eventual some regexp to detect this specific case, to print the log message that is searched by fail2ban.
Cheers, Daniel

There is something wrong:
You show as a SIP response, bu the log files mentions sanity module which can only be used on requests. So, is this the response you are sending back?

sanity can be used also for replies, at least in 3.2.x and devel.
