Problems with WVC80N and remote access (TZO issue?)

Question

I apologize for this "duplicate entry".  I'm a newbie and I think I posted the below in a "Reply" to another Post.  I'm learning.
I have a vacation home in the Sierras.  I wanted a way to remotely check on the snow in the driveway.  I have a Linsys WRT610N router that has been working for a year now.  I recently purchased a WCV80N camera and installed it two weeks ago.  I have SBC(ATT?)DSL service.  PC runs Windows XP.  I also subcribed to a plan with TZO for the remote monitoring.
While I was at the location of the camera, everything worked fine.  When I left and tried to access the camera, most of the time I got the error message about the connection failing because it had "timed out".  I could access the camera at odd hours, late night, weekend, etc.
I called TZO several times to describe the problem and each time they said: "are you at the location of the camera"!!  Duh!!  The rote answer was that it must be my problem.  I'm back at the Sierra home and I've asked a friend to log in remotely.  He has the same problem nearly all the time.  While I am here at the camera location  I can access the camera from the internal IP 192.xxx address.  Access via the TZO MyLinksyscam.com log in is sporadic.
I checked the System log and there are multiple entries for: "UPnP: Internal Gateway UPnP discovery failure.  Then the following:  DDNS: No need to update IP address.  And this goes on every 15 minutes, then the UPnP failure message.
Bottom line:  Does this sound like "my problem" or TZO's???

Answer 1

Sounds like you have the same problems that I had, but the problem is definitely not with TZO, it's your Router. Your Ports might be different than mine but this is what they told me to do:
think you need to open the ports for the cameras.
Follow these steps.
1) open the setup page of the camera IP 192.168.1.99. Click on 'Options' in the side panel. You will find ' Alternate Web Access Port '. If it is disabled then enable it enter the ' Port Number ' - 1024. Save the settings.
2) Open the setup page of the Camera IP 192.168.1.89. Click on 'Options' in the side panel. You will find ' Alternate Web Access Port '. If it is disabled then enable it enter the ' Port Number ' - 1025. Save the settings.
3) Now open the setup page of the router. Go to Applications and gaming. Click on Single port forwarding. If you have any applications there then delete all the applications or uncheck ' Enable'.
Now Go to Port Range triggering sub tab. If you have any application there then delete all the applications or uncheck 'Enable'. Go to DMZ sub tab and if it is enabled then Disable it.
4) Click on Port range Forwarding sub tab. In the application name type ' camera1' . In start and end port type 1024, protocol - both and enter the IP address 192.168.1.99.  Check the box enable.
In second application type the name ' camera2'. In the start and end port enter 1025, Protocol - both and enter the IP address 192.168.1.89. Check the box enable. Save the settings.
See if that works.
