For what it's worth, your employer is probably restricting UDP traffic or has a complex network that doesn't allow uPNP. Don't you think it's weird that iCam worked flawlessly until you moved a computer from home to work? Anyway, it's a network issue of some sort...something the folks at SKJM/iCam have little (actually, ZERO) control over. The information you provided here has been pretty vague...you gave no technical information (such as the uPNP error messages or the camera information requested) to SKJM so they could help you. Frustration is understandable (technology does that), but acting like they don't care to help it's customers is kinda lame. I've been an active member on this forum for years, and have seen them release custom versions of icamsource for people experiencing bugs unique to their systems. For a $5 app, I've never seen better customer service.
