This port and IP information can be useful if you are using the WAN port of AirDial and have a zero-trust network configuration with a firewall device upstream of the AirDial. The firewall may restrict application ports on the inside, or “private side,” of your network for outbound traffic. The below destination IP and ports should be permitted to allow AirDial related traffic.
These port specifications are accurate for firmware 7.5.2.2 or later. For earlier builds, contact GazelleTel customer support.
