Firewall rules, ports, and bandwidth requirements to ensure remote IT support sessions work without interruption.
Remote IT support sessions require a stable internet connection and certain network ports to be open. If you're behind a corporate firewall or use a restrictive network policy, you may need to whitelist some addresses and ports.
Bandwidth Requirements
- Minimum: 5 Mbps upload and 5 Mbps download for a stable remote session.
- Recommended: 10 Mbps+ for smooth performance with file transfers during a session.
- Video sharing: If screen sharing involves video playback, 20 Mbps+ is recommended.
Required Network Access
Our remote support tool requires outbound access (from the managed device to the internet) on the following ports:
- Port 443 (HTTPS/TLS): Primary port for all remote session traffic. This is almost always open on corporate networks.
- Port 80 (HTTP): Used for initial connection negotiation only.
All traffic is encrypted over TLS. No inbound ports need to be opened — the connection is initiated from the managed device outward, so there's no need to configure inbound firewall rules.
Whitelisting Our Tool
If your network uses application-layer filtering or a web proxy that blocks unfamiliar applications, whitelist the remote support tool by application name and/or the BRANDED IAM IP range. Your account manager can provide the specific IP ranges and application signatures to add to your firewall exceptions. Submit a ticket under Technical & Integrations → Network Requirements to request these details.
