Can't open port.

X82 · 8 Oct 2012 at 00:40

I've been trying in vain for days to open up a few ports for my DVR camera. I've gone into my router settings (which is a Trendnet TEW-691GR) and forwarded some ports.
But when I go to www.canyouseeme.org, it always reports the port is closed. Or to be more accurate:

Error: I could not see your service on 81.710.87.251 on port (34599)
Reason: Connection timed out

I'm pulling my hair out as I've never found it this hard to open some ports. Any thoughts?

You could get the same response if the port is open but the camera isn't responding.

Have you tried opening a more common port as a test?

I've tried 8080, 8090, 34567 and the above 34599. I used to be able to view the camera from anywhere in the country. But recently it seems to have stopped. I assumed it would be this, after all, if the port is not open, then I can't view it from another house/city/town. Or am I barking up the wrong tree?

A port opening/forwarding issue is the obvious place to start looking.

It could also be a problem with the camera. Have you checked that it’s accessible from the LAN?

Or it could be a result of deliberate port blocking by your ISP.
