Fortigate blocking incoming SIP traffic for remote clients
I currently have a Cloud PBX running with a public IP address, and I am trying to register a SIP client to it. I am seeing packets hitting the PBX, however all incoming packets are being denied. Please see attached for pictures.
I have also created a policy to allow all incoming traffic from 149.xxx.xxx.xxx into my local subnet. I have tried with and without NAT on both the SIP client and Fortigate.
SIP ALG helper and session helper are also disabled. We currently have a working setup with a pbx hosted behind the fortigate, however we are in the progress of migrating it to the cloud due to power issues at our office location.
Any help would be greatly appreciated!
Thanks in advance.
