can i take 1 as a example?
so you are trying to access a device which is 192.168.1.200:3349?
and hence from outside it should be DDNS:3349 right ?
so can i confirm, your 192.168.1.200 device remote page is configured as 3349 as well ?
and btw, I don't quite understand if the VS provided by Dlink is intermittent, does that mean you are using the VS from TP-Link instead? So your above VS is from TP-Link ?
Before the addition of the TP-LINK to the setup, I tried using DLINK Router itself and the Virtual server would some times work and another time it would not work for any devices inside my own network.
I added the TPLink to the setup so I don't have to use the DLINK Virtual Server functionality (used DMZ only).
Yes the 192.168.1.200 is a Win 7 machine and has software open waiting on port 3349. Port 9 is for WOL and 8888 is for Panasonic IP camera.
Wondering if the problem is still with the DLINK Router (DMZ)??
