Opening ports 80 and 443
I am looking for some direction to pass on to a technician working on a camera system at our house. Please bear with me as I try to explain the problem (I am not proficient in the issues). We have AT&T Uverse, wireless receivers and a WAP. We have installed a camera system for security purposes that uses a windows based server to run the system. The technician has everything working and was trying to set up our mobile devices with an app that allows us to view the video feed remotely. However, he is unable to get the app to work because ports 443 and 80 need to be opened. We have purchased a static IP address from AT&T, which solved the problem when we put the system in last year (re-installed recently after a renovation). The only thing different from what we had last year (when remote viewing worked) was that AT&T came out to install another wireless receiver and while there replaced the modem with a newer one.
My technician repeatedly called AT&T service (talked with 3 different customer service associates; could not get tier 2 help) and got the same instruction each time on what to do, but it did not work. From what I understand, he is trying to install a router behind the RG and needs ports 80 and 443 open for the video system to use. He says opening ports 80 and 443 is not an unusual request and this should be a simple task.
Any thoughts? I am sorry if I am not providing enough information - just not my area of expertise. If there is some key piece of information missing, let me know and I should be able to get it from the technician.
