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)
