Hi Jay / Stefan ...
Just so you know ... with more than one camera, Auto Config Router does not seem to work on my DGL-4100 Router. This is not a v2.1.1 problem - I've had it on all recent versions of iCamSource, and resorted to port forwarding to make it work - which it does and quite well! If I use Auto Config, one of the cameras works fine, all the others report "No Sources Found". So this is not a "trouble report", but rather an "FYI". Thanks.
