Configuring the network for screen sharing
Network administrators need to configure the network so users can share their devices’ screens. Use the following information to configure the network for screen sharing to displays that have SMART Screen Share. This information applies when using AirPlay, Google Cast, Miracast, and SMART Screen Share client apps to share.
Important
You’ll also need to configure the network so all of iQ's features function properly. See Configuring your organization’s network for a SMART Board display with iQ.
SMART strongly recommends that you contact the network equipment manufacturer for more information about network configurations that support screen sharing.
For remote connections, the receiver and client devices need to be able to access the internet through these ports:
TCP 80
TCP 443
UDP 123 (Network Time Protocol)
Note
Even if your network is open, the ports listed on this page need to be open for SMART Screen Share.
AirPlayEnable the following ports for using AirPlay when screen sharing:
Port | TCP or UDP | Description |
|---|---|---|
53 | UDP | Domain Name Server |
80 | TCP | Outbound HTTP |
443 | TCP | Outbound HTTPS |
554 | TCP/UDP | Real Time Streaming Protocol (RTSP) |
3689 | TCP | Digital Audio Access Protocol (DAAP) |
5353 | TCP/UDP | Multicast DNS (mDNS) |
7000 | TCP | Picture sharing |
7100 | TCP | Display mirroring |
7010 | TCP | Display mirroring |
7011 | TCP | Display mirroring |
Bonjour is the Apple standards-based network technology designed to help devices and services discover each other on the same network. Although Bonjour is most commonly used to discover services and devices on smaller networks, it can also be configured for use on larger networks by using a Bonjour gateway or similar technology. Networks using such features for AirPlay should be configured to advertise both _airplay._tcp and _raop._tcp services. Even though it’s possible to use advanced DNS configurations for advertising some Bonjour services on enterprise networks, AirPlay requires live device discovery using the methods described in AirPlay discovery.
Google CastEnable the following ports for using Google Cast when screen sharing:
Port | TCP or UDP | Description |
|---|---|---|
80 | TCP | Outbound HTTP |
443 | TCP | Outbound HTTPS |
1900 | UDP | SSDP |
5353 | TCP/UDP | Multicast DNS (mDNS) |
8008 | TCP | Google Cast Discovery |
8009 | TCP | Google Cast Discovery |
SMART Screen Share client appsEnable the following ports for using any of the SMART Screen Share client apps when screen sharing:
Port | TCP or UDP | Description |
|---|---|---|
80 | TCP | Outbound HTTP |
443 | TCP | Outbound HTTPS |
55200 | TCP | SMART Screen Share client app |
5000 | TCP | Display mirroring |
47000 | TCP | Audio mirroring |
7010 | UDP | Display mirroring |
7011 | UDP | Display mirroring |
49228 | TCP | Display mirroring |
54780 | UDP | Display mirroring |
62527 | UDP | Display mirroring |
41600-41609 | TCP | The SMART Screen Share client app selects and uses an available port. |
When screen sharing over the internet with the SMART Screen Share client app, add the following URLs to the network’s allowlist:
