ports Forwarding issue

I use ATT DSL with ATT’s 2Wire router. After much research the port forwarding to DVR (named H264 w/ no support or website that I can find) is well and when I remotely jump onto my neighbor’s network, I can access my Camera.  I can access my camera locally through LAN too. However, the only known ports I needed are 80 and 2000. I cannot access my cameras from any other Internet hooked up computer. I went as far as to load supplied software (from DVR system H264) on another computer. The app comes up and connects to my home, but no video pictures?

Can someone assist in additional ports that may need to be forwarded or local ports that may need to be opened?

I don't understand what you are saying here.  When you go from your computer to your neighbor's through wi-fi to your camera, you ARE accessing your camera from the Internet.

I am confusing. I use my laptop from home. I can access my DVR cameras on local LAN. I use the same laptop and connect to my neighbor’s wireless network; I can access my DVR and cameras. I use my work computer or my friend’s computers and I cannot see video.

Sounds to me one of two things:

1.  You need to install the client software onto the other machines to be able to see your camera.

2.  You are using different versions of web browser.  check the versions by looking at help, about from the browser's menu.

To give you an example, I have a Panasonic wireless video camera.  To access it in the browser I had to install the Panasonic software that converted it to a format that the web browser understood.

The other problem I have is that the Panasonic software works badly with Firefox and not at all with IE8.

What is connecting your home network to internet? A router/firewall? if so which make and have you allowed all required ports to connect to it?

From your work or some other place, do this;

1. Open a command prompt.
2. telnet <nn.nn.nn.nn> 80 and hit enter, see if you get connected (if yes, then you should see a blank screen).
3. telnet <nn.nn.nn.nn> 2000 and hit enter, see if you get connected (if yes, then you should see a blank screen).

Thank You Snibborg and rsivanandan,

 I will try these options and report back in several hours.

Rsivanandan; telnet proved very useful. I could not “get in”. I punched holes in my computers firewall. Turning off the firewall was no good enough (Microsoft thing). Then I was successful in telnet’ing ports 80 and 2000.

Snibborg;  iE browser version. After testing this, I did find different reactions depending on Browser and version used. Firefox displayed html code and with iE I was able to bypass most issues by holding down the Ctrl key whilst clicking enter/go to access the site.

Next issue. When I telnet port 2000, the command window only stays open for about 30 seconds, then it goes back to command prompt. When I telnet port 80, the command window stays open. When I iE browser into the DVR, the control window/GUI only stays open for about 30 seconds and the returns a notice “Socket close!”

My problems are not completely solved; however, a monitor or expert will have to advice if original problem is resolved for purposes of awarding points.
Any addition troubleshooting direction will be tried and appreciated.

Lets not get into a situation about applying points.  At the end of the day do you believe that the problem has been solved?  If the answer is yes, then by all means allocates the points.  However, if you are still have not got the problem solved, let us know what parts of the issue are still outstanding and let's get it sorted.

We are not here to accrue points (although that is a nice byproduct), we are here to solve problems.

We look forward to hearing more details.

Telnet was only used to see if you're able connect, that's all. So do not worry about it being open/closed etc. So the initial connection issue is resolved.

Now, what else is hindering, are you not able to view it properly?

When I iE browser into the DVR (http:// nnn.nnn.nnn.nnn) It opens the DVR camera GUI, asks for username and password, I supply, then returns a message “Socket Close!”

When I use the supplied software from manufacturer, It opens the DVR camera GUI, asks for username and password, I supply, then returns a message “Socket Close!”

Again, this is all from a remote location. The local LAN works. Does this lead me to the manufacture? I hope not, they are unreachable as far as I can tell. Or the ATT 2Wire router, I have read (www.portforward.com and www.mediasmarthome.com) they are not the friendliest router.

What make of camera is it.  I suspect that you need another port open for password authentication.  It explains the situation where you can log in with your laptop, as it is somehow cached.  When the password fails, it closes the socket.  Can you put in a blank password for the camera and see if it works?  That would confirm it.

Oh, good turn Snibborg.  I will try the no password idea and search further for possible additional ports that are needed. As I am at work right now, I will make adjustments in about six hours from now. That will not keep me from continuing to research these issues.
I was surprised and happy to see that Experts-Exchange had a forum devoted to Digital Living/ Home Security. I don’t know why I didn’t notice it before.

I'm beginning to realise that EE has a forum for everything except porn.  Or perhaps they do have and I haven't found it yet ;).

I look forward to the next update.

YES,
Working well. Set password to “blank” No work. Rebooted DVR. Yes work.
What a long road, as typical, no manufacture support from DVR or router. It does take (I learned long ago) sites like Experts Exchange to find real world answers.
Thank You Snibborg and rsivanandan!
This wasn't possible for four weeks until I asked and you answered.
I have read this site for hundreds of answers and this time, I needed to Ask.
