I emailed regarding a problem which I encountered with one of my iCamSources and thought I'd raise this again in the forum in case someone else has the same problem. I have a USB camera set up at my office and all was working perfectly until one day when I could only access the iCamSource on a WiFi network, not 3G. I wasn't aware of any changes to my office network but it transpired that we had changed ISP. We now have 2 ISPs each through their own Cisco Systems enterprise type routers which I have been advised are configured in exactly the same way. On one router, I am able to access the iCamSource on WiFi and 3G yet on the other, I can only access through WiFi. I understand that fiddling around with these routers is difficult and the GUI is very unfriendly. Is there a work around that I could explore?
