We actually have two internet services. Cable and Fiber. Both have static IP addresses. Cable has a cable modem, and fiber has a fiber modem. Both modems are connected to a single router. It's a dual-wan router that takes both services and provides and "blends" them to provide a "normal/single" internet connection to our network. I know this sounds weird but again, everything other than iCam works great. The router uses "persistence" to make sure a device isn't suddenly using a different external IP address one second to the next. Based on how iCam works, do you think a change in IP address could lead to several days of not-functioning? And then suddenly start working again for a few days? Does your server refresh that slowly or something?
The local IP on each computer is static. However, we have two external IP addresses. They are also static, but persistent -- meaning when accessing the internet, a computer will not switch IP address for a given session. Later on however, the router may assign a different external IP address for use for a different purpose.
This system works well for everything inside the network, including security cams / DVR, voip phones, computers. I do not believe this is causing any issue with iCam because prior to having two external IP addresses we had a single one and the iCam issue was exactly the same.
Clicking stop / start does not make a source appear if it's not in the mood. Again some days a few sources will work, and some days no sources work. And once in a while all sources work. It seems random, but whatever the situation it seems to be like that for an entire day or two.
Nothing so simple I'm afraid. As long as ports are opened on the router and iCam Sources are assigned the appropriate UDP range, everything works superbly. But I don't want ports open. With ports all closed, it seems sometimes it works and sometimes not. Would changing IP addresses cause this?
And then, like magic, it all stopped working. Now, about a week later, no sources can be found for several days. Nothing that I'm aware of has changed in the network. What could it be?
You know, this is weird. Maybe you can explain it. But initially when I tried connecting from outside to my inside network, I got the no sources error. So I assumed you need open ports or a VPN. The VPN didn't work, so I thought I was just out of luck. A few days later, one of my sources started showing up. A few days later a 2nd one. And then a few days later all of them.
So now all my iCamSource Pro feeds show up on iCam Pro with no special network settings. Thanks! How did this happen after several days? It's like magic!
Open ports on routers can be a security risk, so I avoid them. UPnP and NAT-PMP are disabled in my router.
To access my network from outside the office I use a VPN that is built-in to the router. Over the cell (AT&T / LTE) network, I connect my iPhone to my router using L2TP VPN and am able to a access other resources on the network such as screen sharing and DVR security cameras. However, iCamSource Pro cameras won't show up this way -- "Broker Connection Error: Your network may be preventing you from making a UDP connection to the iCam Broker Server."
When I connect on WiFi to the network everything works fine. Why won't UDP go over a VPN like this?
I have 4 cameras (3 iMacs and 1 Mac Pro with Logitech USB cam) with iCam on my iPhone 4S. Yesterday suddenly iCam would randomly beep and zoom out to show all 4 cameras. I would click on a camera to zoom in and hear the audio, and within a second or 2 it would beep and zoom out. I tried quitting iCam and even powering down my iPhone, but it made no difference. My iPhone works perfectly well otherwise.
Today, it's still doing the random beeping every few seconds, but it's staying zoomed in most of the time now that I turned off the hires option.
