Answer 1

Not sure if this will help, but people across the country are experiencing difficulties with the roll-out AT&T/SBCglobal/Comcast ISP. They used to pass Internet traffic through their lines like telephone calls, but now their routers have a number of global security measures. These routers now must be programmed for IP passthrough, which assigns devices their own ISP based on the device IP plus an additional ISP identity. In addition, the routers must be programmed to open the ports required for the specific services that the user wants to enable. They couldn't figure out if the higher security settings should be default, or not, so certain events trigger the higher security settings, like traffic from foreign network or an http request within another http request, etc.
