I have users with dynamic dhcp ip address continuously changing and I have Freepbx system on the AWS behind AWS firewall. I have to white-list every user’s ip address each time it changes.
It’s hectic approach. I need a proper solution for this. it’s difficult when you have 100 of IP Phones and they are all continuously changing ip schemes.
Hello, perhaps you could open the AWS firewall widely for SIP and enable the FreePBX responsive firewall to allow valid users while denying bogus calls/registrations.
