Camera works in iCamSource but can't see it on iPhone

[MyIcams]

I have 3 cameras:
Logitech USB webcam, an Axis IP wireless and a TrendNet IP672WI.
When I setup the cams in Source it works perfectly (all 3) but when I look at it on iCam the TrendNet does not show (but the Logi and Axis works).

Any Idea?

It's most likely a port forwarding issue. Did you enable uPNP in your router, and check the "auto router config" box in icamsource? Or, the alternative would be to set up manual port forwarding.
