My humblest apologies and many thanks for all your help with this issue. On the bright side, I got to explore and learn all about the 3801HGV and all it's settings a lot sooner than I had expected. Except that I feel really stupid, and bad for all of the grief and extra work that I have caused everyone trying to help me. Now that I have made the correct adjustments to the addresses I am able to access my cameras from my work computer as before, so all is good now. It was a stupid error that I should have caught, and to make matters worse, when I changed all of the URL's I just copied and pasted the address for the other two shortcuts from the first one I changed. I had made it 72, when it should have been 172, and I just never caught it as I guess my brain saw what it wanted to see, all of those other times I had checked it. While just rechecking all of my settings I noticed that I had dropped a 1 off the very beginning of my public URL address. So, when ever any changes were made I would just go to the shortcuts and make the necessary adjustments to the properties to get them working again, which I had done after the uverse install. On my remote computer (work computer) I had made shortcut links in my browser for each camera several years ago when I first installed these cameras.
The more I thought about the more it just didn't seem right and make any sense to me so I decided to go back over all of my settings.one more time. You are absolutely correct that it doesn't make sense that I can connect to these cameras with my phone and not my remote computer. I'm thinking that maybe I should connect my DLink router back in through the DMZ and reconnecting everything back to it as it was before, but I'm not even sure that would work. They will not connect using the broadband address of 172.xx.xx.xx:xxxx. I've tried everything I can think of including putting them in the DMZ, to no avail. And I find that odd since this address is the same exact address that I have plugged into the app on my phone.where it works great.
I can connect to them from my local computer using the local IP (192.168.1.xx:xxxx), but when I type in the broadband address with the port number it will not connect.
I've managed to set them up within the 2wire RG with the port forwarding and all, and can connect to them from the LAN, as well as the app that I have on my Android phone, but I cannot get them to connect from any remote computer. Since switching to Uverse I cannot get my three Trendnet IP cameras to connect remotely, as I could before with my previous neetwork setup.
