2 ways:

·         is_in_subnet() - http://www.kamailio.org/docs/modules/3.4.x/modules/ipops.html#idp42416

·         Add the IP and mask to the address table and use allow_source_address() - http://kamailio.org/docs/modules/3.1.x/modules_k/permissions.html#id2528610

Subject: [SR-Users] Need to validate a IP address with subnet mask

Hi All,

I want to validate a IP address in kamailio for requests coming from different IPs. I have browsed and found permissions module, however is there a way where i can directly compare a source IP address to an address stored in an avp and get a true or false value.

something like this


Thanking You,
Sunil More
