Hi everyone,

I'm running into a persistent connectivity issue with my ManageEngine MDM setup and could use some advice.

My Setup:

• Installed ManageEngine MDM on my office PC (acting as the server)
• Office has its own firewall configuration
• My mobile device (endpoint) needs to connect from outside the office network
• I don't have access to the office WiFi for my personal device

The Problem: The MDM server and mobile device need to communicate, but my phone is being treated as an external device by the firewall. Even after configuring NAT (Network Address Translation) to try to route traffic properly, the connection is still failing.

What I've Tried:

• Confirmed the MDM server is running properly on the PC
• Configured NAT settings to allow external connections
• Mobile device still can't establish connection - NAT configuration didn't resolve the issue

Questions:

1. Has anyone successfully deployed ManageEngine MDM with devices connecting from external networks when NAT didn't work?
2. What specific firewall rules or port forwarding configurations are required beyond basic NAT?
3. Are there alternative connection methods that bypass these network restrictions entirely?
4. Could this be a ManageEngine-specific communication protocol issue rather than just a firewall problem?

Any insights would be greatly appreciated - the NAT approach seemed logical but didn't solve the connectivity issue.

Thanking you in advance
