I have successfully configured my camera and got everything working and then, since it's easier to connect directly to the camera rather than using the mydlink site, I noticed that since we're using DHCP, that the local IP address had changed on me. I tried unsuccessfully to configure the NetGear router to reserive an IP, but that didn't seem to work. So then I decided to assign a static ip from the camera configuration network setup. Now the ip remains, but for some reason, this broke the ability to send email from the camera??? I set it back to DCHP and email works again.
Also, strangely, the MAC address of the camera as recorded on my NetGear router is different than the actual MAC address. It differs in the 1st 2 numbers (B0 vs B2). What the heck is going on here?
