12 Reference Information - Network Traffic

When AudioFetch Express is used in Access Point Mode, the built-in Wi-Fi is compatible with all
required network traffic to/from connected mobile devices.
However when Wireless Client or Wired Only modes are used to connect to a pre-existing network, it
is important to ensure that the required network traffic is able to flow between AudioFetch Express
and mobile devices running the AudioFetch App.
When in Wireless Client or Wired Only modes, AudioFetch Express typically works out of the box on
simple networks such as when connected into a single small business wireless router using the main
(not guest) WiFi. More complex networks may require configuration adjustments (firewall, etc.).
Information in this section is provided to assist IT/Network personnel when such adjustments are
necessary.
Network traffic used by the AudioFetch System, unless otherwise noted packets are unicast between
IP address of the Mobile Device (running AudioFetch App) and IP address of AudioFetch Box:
