Here is the situation. I have a customer with an AvTech 8 Channel DVR. We installed this system about 15 mos ago. We chose this at the time because the customer is on a Mac. So anyway fast forward to now. He had his DSL Company come out and swap a modem/Router and install a Gigaset 762. This DVR has its own Wan Static Ip address and for about a month everything worked fine. Now he is unable to see the web login page. We can get to the web log in page from our Blackberry Browsers but no where else outsite of the router. (Inside the home network any computer will pull it up) We tried to call his DSL tech support and they can see the Web Log in Page. But from friends in other homes/Office we just get a page that cannot be displayed.
We can get in via Video Server from outside but not the webpage. We have tried all versions on IE, Mozilla.
So basically the only browser that will connect outside is the Black Berry, and of course the Tech Support guy. We have checked everywhere for filters, etc and cannot come up with anything that makes sense to us.
Also this customer has 5 static IP's to his house and we tried changing them and still come up with the same result.
Any ideas of what might have happened?
