List of Ports to be opened in Firewall

For device discovery

  • If your device only supports WMI, you will need to keep the ports 135 and 445 open.
  • If TCP is supported by your device, open the ports 5000 - 6000.

For data collection and monitoring of devices

Open the following ports in your firewall to ensure uninterrupted monitoring of your devices.

  • SNMP-161(UDP) - Bidirectional
  • SNMP Traps- 162(UDP)- Unidirectional (From monitored device to RMM MSP server)
  • Telnet- 23(TCP)- Bidirectional
  • SSH- 22(TCP)- Bidirectional
  • ICMP- Used to check the availability status and to add a device. - Bidirectional
  • Default syslog port 514(UDP)- Unidirectional (From monitored device to RMM server)
