while doing some tests, i noticed that one of my proxies started to
receive lots of register requests with different user names starting

from ip 202.82.16.99 which according to traceroute is somewhere in
china.

Juha,
I think we should be specially careful about black-lists. We receive
many of these attacks in a per-day basis and a lot of them are from
residential addresses or university, so I'm guessing some kind of worm
or trojan performing the attack from various IPs.
If you have the time, try
I'm second for fail2ban. I block IP addresses with failed registration
attempts for 1 hour. Here is my setup:
kamailio.cfg:

if(www_authorize(, subscriber) 0) {
if($rc == -1) {

I watched live an attack on voipuser.org while running 3.1 before
release. It lasted 18 hours. I didn't want to ban it because was useful
for testing and see if it reveals any weak. In most of the cases it hit
pike module. I got some data and plan to make an article about it soon.
Anyhow, as

This is, pike module inserting dynamic rules in iptables. Opinnions?
You could spawn a Perl script that does it, but it'd be kind of slow.

Oh, I did not realise it is so
