Hardware requirements for PC and display using AllSync

AllSync lets you wirelessly share content from almost any device, but smooth performance depends on meeting the right hardware and network requirements. This guide is for IT admins, AV integrators, and anyone setting up AllSync in schools or businesses. If you’re troubleshooting connection issues or advanced network setups, check the troubleshooting section below.

Before you start

  • Make sure you have admin rights on your devices and network.

  • Consult the requirements for your device below before following instructions.

Network requirements

  1. Bandwidth: Minimum 20 Mbps per device; 50 Mbps recommended for HD content.

  2. Connection: Wired or wireless; host PC and clients must be on the same network.

  3. Internet access: Needed for activating AllSync receiver and installing updates. Ensure firewalls/antivirus do not block access.

  4. Protocols: Enable Bonjour/mDNS and multicast on your network.

  5. VLAN/subnet: Devices must be on the same VLAN/subnet for AirPlay. For cross-subnet connections, set up a Bonjour Gateway.

  6. Required ports:

    • mDNS: 224.0.0.251 port 5353 (UDP)

    • AirPlay: TCP 7000, dynamic TCP ports, UDP for RTP audio

    • HTTP/HTTPS: TCP 80/443 for direct video links (e.g., YouTube)

  7. Multicast groups: If using multicast, include all AirPlay devices and clients, and enable IGMP Snooping.

Enable AirPlay and Bonjour Gateway

AirPlay applications use a direct connection method through the local network. The AllSync receiver is directly connected to Apple devices.

  • AirPlay requires sender and receiver to be on the same VLAN/subnet.

  • Apple's AirPlay cannot cross subnets/VLANs natively. To connect across subnets, configure a Bonjour Gateway or AirPlay proxy.

  • Bonjour/mDNS and multicast must be enabled. Apple’s Bonjour uses UDP port 5353 and IPv4 group address 224.0.0.251.

  • Bonjour traffic is link-local and not routed by default. Bonjour Gateway allows AirPlay across subnets but will show all AirPlay devices on the network. We recommend changing broadcast names and adding AirPlay passwords for security.

  • Routers cannot use multicast routing to redirect the traffic because the time to live (TTL) is set to one, and link-local multicast is meant to stay local by design.

Multicast groups

  • Multicast groups can help manage network load with many AirPlay devices.

  • Ensure all relevant subnets/VLANs and devices are included.

  • Enable IGMP Snooping so only group members receive multicast traffic.

Troubleshooting

  • Devices not found: Check all devices are on the same VLAN/subnet and that multicast/Bonjour is enabled.

  • Poor streaming quality: Verify network bandwidth and reduce simultaneous streams.

  • AirPlay not working across subnets: Set up a Bonjour Gateway or AirPlay proxy.

  • Firewall/security issues: Allow required ports and protocols through firewalls and antivirus.

  • Unsupported environments: AllSync Windows receiver does not work in virtual machines or terminal services.
