It seems contrary that you would set this to "share a public IP address" - what does this do and once you have reconnected, do you reset this back to the off mode? so, my connection sharing is set to “Off (bridge mode)”.

The only way to get rid of it was to click "ok". In a minute or so, out of nowhere a file downloaded to my dl folder. It had ".htm" at the bottom of it. I sent it to the trash and emptied the trash. By the time I did this, another ".htm" went to the dl folder. I sent it to the trash also and emptied it. My computer is the only one at my house and I have no iPhone or i-anything. So what happened?

Here's what the smart guy at Apple said: This may be a problem with my Time Capsule. They default to Bridge Mode, when they should be set to DHCP and Nat. This is in the documentation exactly nowhere. Go to Airport Utility. Click on the icon for your Time Capsule. Click Edit. Choose Network. Change Router Mode to DHCP and NAT. Click Update. There will be an error code: DOUBLE NAT. Select IGNORE. Yay! You're done. All of these did not work for me.

After a restart it was up running again, so I thought this was not a problem. But since this was such an odd box ive never seen before, i screenshooted it. A month later, when I got my internet bill - I completely chocked! I had expanded my consumption with $ 2800, and could not believe it! Ive never did it before in a year! I called my internet company, and they told me that all this was used in one day. One day! And that day was one week before I got this message up on my mac, and that day I was on vacation without my computer: someone had hacked my IP address. That screenshot I did, saved me from paying all the expenses! Just a reminder and warning:

I am not using airport or wi-fi. I am using ethernet. I rebooted the router, it did not help. The other computers (PCs) on the same router are okay. The only things that are different are that I unplugged my iMac and took it to another location for work. At that location, I used their wi-fi twice, and I set up an ethernet-based mini network as a temporary way to connect to another computer to transfer files back and forth... I didn't change any network settings... After reading some of this, I am thinking that connecting via ethernet is the cause of my problem, since I got this message as soon as I plugged it in back at home. I used the Network Assistant and it told me to contact my provider. I am having the same problem. I am not using airport or wi-fi. I am using ethernet. I rebooted the router, it did not help.
