I have "Great" news...Please share this with all in the Community, and on other areas dealing with difficult issues regarding X10 Cameras. I just completed (with the help of and X10 Tech name Bill) port forwarding for my XX40 Airsight Camera. Bill called me, three consecutive days, to guide me through the port forwarding process. I have "NEVER" experienced this kind of positive, patient, and expert assistance from anyone, including paid services, before. Hats off to Bill!
Let me pass on some information here that can be helpfull, regarding forwarding a camera port, via a 2wire modem (ATT) type. The modem log-in (my case) was on the side of the modem box. It is called (in my case) the Modem Device Access Code.
Another thing; when I started the port forwarding process, after logging in to my modem, firewall tab-I had to select applications and pinholes...Since this area was not highlighted (like most selectable items are) I got hung up. You can place the mouse directly on pinholes and Applications and you will see that you can double click on it to advance.
finally; if you need to view your camera on your smart phone at home, type in the address (internal ip) as shown in the browser along with the (colon ) and the port that you forwarded ie192.178.3.251:followed by whatever the port number is. All this info will be in your browser when you bring your camera up at home.
When you are away from home using 3 or 4G smart phone; type in your public IP (you can find this by typing "What is my IP" in your browser) folowed by (Colon) and your port number that you forwarded
I don't think I would have been able to complete the port forwarding process without Bill...I will try to do this on my own when my next camera arrives in the mail...Wish me luck. Hope this info helps ...
