Hello,

for sake of completion, using the src_ip keyword works with network addresses:

if(src_ip==1.2.3.0/24)

Cheers,
Daniel

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

$si==192.168.2.0/24

Thanking You,
Sunil More
