I have got the cam (logitech 4000) working when I'm on my LAN.

I get the message "couldn't connect te server" when I remotely (via Internet)open de URL to the cam.
The error message tells me that the port-mapping etc should be working.
Should I open both ports on my ADSL router (7776 and 7777)? Any other reason?

Another question: how do I enlarge the image? It's so small.
