Hi, It looks from the code that the subnet IP address must be masked. https://github.com/kamailio/kamailio/blob/master/src/modules/ipops/ipops_mod.c#L393
if ((ip->s_addr & ipv4_mask) == net_addr.s_addr) return 1; return 0; So 10.1.1.0/24 will match 10.1.1.241 but 10.1.1.128/24 will NOT match 10.1.1.241 Regards, Hugh On 14 March 2018 at 12:39, Daniel-Constantin Mierla <[email protected]> wrote: > Hello, > > maybe it is what Hugh said in his response, respectively that the subnet > needs to have the lowest bits masked. > > Can you run with debug=3?
