Configuring your computer firewall for use on Livewire networks

Updated by Bryan Jones


This document applies to any computer which uses the Axia IP-Driver. Primarily this affects Windows computers.


For computers operating on an Axia network, it will be necessary to manually configure firewall settings to allow UDP and TCP communications between the PC and the Axia network on specific local ports. Without these firewall rules, programs like the IP-Audio Driver may appear to function normally. Still, they will not be able to exchange audio, GPIO, or advertisement with the Axia network.

This document outlines the ports needed for the IP Driver to function correctly. There are far too many operating system combinations to give specific instructions for each; however, the TCP and UDP port information is the same regardless of the OS. Also, many 3rd Party programs have firewall components. Norton and McAfee are very common and can also block ports needed for proper operation.

Hence, the general nature of this document.

If you are having problems, the first tip is to disable everything. Turn the operating system firewall OFF and either turn off or uninstall any 3rd party programs. Then selectively turn these back on to know where you need to create rule exceptions.

Ports Used

Regarding AES67

Ports used for AES67 audio are user-definable. That is to say, while Livewire uses port 5004 for all audio packets, the user can define AES67 audio ports. You will need to adjust your firewall settings to accommodate situations outside the Livewire specification.
