Ports forwarding without setup

I heard that UPnP could be a security issue, so yesterday I disabled it. I have port forwarding turned on for 2 applications, however I'm able to use other ports that are not currently explicitly setup (VNC on port 5900, RDP on 3389). I probably set them up in the past However, I can't find where in the configurations they are. When I try to setup a new port forward (on port 5900) I get this error message:
The specified port(s) are being used by other configurations. Please check your configurations of Remote Management, Port forwarding, Port Triggering, UPnP Port Mapping table, RIP, and Internet connection type


When I RDP or VNC I'm forwarded to the correct computer (as if I had set it up before).

Current setup:

    Any idea why I can access my computer remotely, despite the ports NOT being forwarded?

  • Should have mentioned: WNR2000v2, Firmware Version V1.2.0.6_36.0.58
  • Yes, under "Router Status--> Internet Port --> IP Address" I have an IP address that was issued by my ISP.
  • 2cents. READ other thread on this model with similar issues people are having on port forwarding
  • I'd suggest you start by resetting the unit to factory defaults & then reconfiguring - there have been cases reported of forwarded ports not being displayed, and a reset would/should clear any such settings out.
  • I've just reset to factory settings. Seems to fix it. I think there is something wrong with the disabling of UPnP.
