on my Yawcam computer, behind my router, I was getting the 'Need signed applet' error.
On another computer behind my applet, I was getting the stream on the public IP address, but not on the http://192.168.0.100:80
After restarting Yawcam, lost it on the remote computer (both public and local addresses - both with "Err! Check Host! Need signed applet), and can see on the Yawcam machine on the local address (http://192.168.0.100:80
I was loving it until that! It's a great utility you've created.
