xx.xx.xxx.xxx is my public I.P.
What kind of filtering are you doing? Iptables?
Rather than playing 'wack-a-mole' with hackers, my first line of defense
is to 'white-list' just the few legitimate connections between my clients
and their SIP providers.
If your situation requires remote and mobile access, can you at least
'black-list' certain countries with a propensity for hacking? Do you need
access from China, North Korea, Iran, etc?
You can eliminate a very large percentage of hacking attempts with just a
few rules. Then you can focus better on the remaining threats.
