What is it?
This module prevents attacks from any host reported as an aggressor on the community list, by filtering SIP UDP packets automatically. It checks any new connection against a community constructed DNS based block list of offenders. 1
How can I use it?
Once installed the filter will be active whenever you have fail2ban enabled in your Issabel server. For that reason, it requires both iptables and fail2ban services to be up and running.
- This module does not require a license. It is available for free to all Issabel users [return]
