Network requirements
For optimal performance, verify that the network where AirSync and the AirSync client operates has the firewall configured to allow the following connections:
Relay connection
Relay connections are used in scenarios where direct connections between devices are not possible due to network configurations.

Local Connection (Direct connection)
Establish a network connection directly between devices within the LAN without relying on external servers or services.
- TCP 5100
Remote Screen
- TCP 7000
Video/Audio (WebRTC)
- Random UDP ports in the range of 32768~65535
Mirror
AirPlay, Googlecast, and Miracast do not require access to the Internet.
-
AirPlay, Google Cast
- Does not work in different subnet/VLAN
- Random UDP ports in the range of 32768~65535
-
Miracast
- Use Wi-Fi Direct (WiFi P2P). Does not require wireless AP.
Bandwidth requirements
To improve image quality and user experience, ensure that the network bandwidth should be at least:
- 5Mbps for a WebRTC session casting on full HD, or
- 15Mbps for a WebRTC session casting on higher resolutions
The casting resolution is determined by:
- Resolution of the sharing screen, and
- If "High image quality" setting is active
If the "High image quality" is:
-
OFF:
Max casting resolution up to QHD (2K), if the device sharing its screen supports this resolution.
-
ON:
Max casting resolution goes up to UHD (4K), if the device sharing its screen supports this resolution.
To compute for total network bandwidth usage, multiply the minimum bandwidth per session by the number of concurrent sessions.
Miscellaneous info
Note the following information for the systems mentioned below.
- Limit WebRTC port range in Chrome
Chrome policies (WebRtcUdpPortRange) can limit the range of local UDP ports used by WebRTC. Refer to setting UDP port ranges in the following page:
