Thanks, drgeoff. I spent about three hours last night researching the issue and came to the same security hole conclusion. I made quite a few changes to my default settings, and I think I know of the change that you are referring to. Can you please confirm that after these changes, I should be good to go now?

If you think I should make any other changes, please let me know.
Also, I received about 4 or 5 total calls from that "number". Is it possible that my network is already compromised? I'm a little worried that someone may have managed to get onto my network and that changing the Obihai settings will not fix that problem.
