Sorry I am new to the forum so let me know if I add this topic to the incorrect section.
I am using an RB1200 v5.21 and trying to setup a firewall to block unwanted SIP traffic / attacks to my Asterisk server, withouth blocking the IP´s from the genuine customers.
Have tried to block IP addresses after 15 x content="SIP/2.0 401 Unauthorized within a certain period of time but eventually this will also block my genuine customers as sip traffic alway responds with content="SIP/2.0 401 Unauthorized before connecting. (also tried same method with 403 Forbidden)
Does anyone know a good method to block unwanted SIP traffic on the Mikrotik Firewall without blocking the IP addresses of genuine customers?
Also allowing only the customers IP addresses is not an option as they take their VoIP phones with them to different locations.
