Remote security camera - Not port forward issue, please read
I am having a frustrating problem connecting to my remote security cameras (ISP is not AT&T Uverse) from my home network (AT&T Uverse). Any other network I connect from works fine - wireless hotspot, phone hotspot, neighbors wireless. I know how to configure port forwards and have verified that they are configured correctly by testing on the other networks. Previous to AT&T Uverse I had AT&T DSL and it worked fine. So now the only difference is the Uverse and an NVG510 device.
The cameras are Honeywell and port 8000 is default. The port has since been changed to 4000. To date I have done the following:
- Called tech support. Agent did a remote login and added a custom service with global port: 8000, base host port: 800, protocol: both. He did not assign the custom service to a device - he only created it. When asked about an explanation for what he did he seemed hesitant and did not provide any detail. This change allowed the cameras to be used for about a week before returning to the current non-working state.
- Changed port to 4000 because there was some information suggesting AT&T uses port 8000 for other applications. This change did not fix the problem.
- Bridged NVG510 to Cisco E3200 to eliminate the NVG510 router as the source of the problem. This change did not fix the problem.
- Repeated calls to tech support who now insist that the problem is either port forwarding or not within the scope of their support. They want me to pay for Connectech service.
I've done a lot of searching on this forum and there are a lot of topics that apply to the case where the cameras are behind the NVG510 and port forwarding is the issue - this doesn't apply to me as I see it. I found only one or two topics where someone had a similar issue to mine, but they had few responses and zero resolutions.
Does anyone have similar issues or hopefully a fix?
