Unauthorize Traffic

Added by Rumman Khan almost 10 years ago

Hello Team,

Few month ago ,i noticed unfair uses of minutes/Voip in my vicidial server . I saw some unauthorized traffic from asterisk CLI .

we decided to go for Autodial 3.0 as it has "Fail to Ban" application and hoping for better security.

But again I saw hacking attempt and unfair uses of Voip Minutes.

Hi,

You can block the IP address on IPTABLES on which the extension 6019 is registered from. Try to change also your dial prefix.

Hello

Please guide me to Block IP address.

There is heavy traffic resulting in voice breakage. I have to block this IP -62.141.45.182.

Hi,

Try command below instead. After saving don't forget to reload/restart your iptables.

-A RH-Firewall-1-INPUT -s IPAddressYouWantToBlock -j DROP

Ryan

Hello striker24x7,

Thank You for your help , iptables helped me a lot .It works fine. I used to block the unauthorized IP address with help of IPtables.

but there is one problem everyday hackers keep changing the IP Address and I have to block everyday.

Is there any automated method/script to do this.

My Goautodial Version is 3.0 and I don't know why Fail2Bain fails in blocking these IP address.
