Connecting to Q'Center behind NAT

Post by derekzeanah » Sun Feb 10, 2019 2:18 am

So here's my situation:
  • 3 NAS devices on local network
  • All local QNAPs connect to Q'center cleanly.
  • Want to monitor a remote QNAP device without leaving a VPN open or opening a port in the remote firewall for compliance reasons. So I'm going to allow it through the local firewall.
  • Configured remote QNAP with DDNS hostname
  • Created a firewall rule to allow connections (ports 443, 873, and 8899) from that DDNS hostname.
  • Connected from site via 443 - it works.
  • Added a registration code in Q'Center
  • Installed and ran the connect to Qcenter app. It connected and installed the agent.
  • Now, when running the agent to try and connect I get the error message "Failed to Add."
  • I've tried changes like connecting with/without https, using 8080 instead of 443 (with and without https), changing the code to something shorter and just lower case. It's always "Failed to Add," or can't connect if I mismatch the https:// and port number.
I'm at a loss here. I feel like the app should be working so there's something I'm doing incorrectly, but I have no idea what that might be.

Firewall logs show it is being allowed through (as suggested by direct connections).

Looks so simple here

I assume you are not confusing it by using uPnP and NAT
