AT&T/SBC is my Internet provider, but why would they have a ESTABLISHED connection to my network.

It's TCP, both ports ephemeral, so no clue at all. Using something like 'netstat -antupe' will show the application or script interpreter and its PID. That'll give you more details.

It was Skype.com that had a ESTABLISHED connection, I had to shut skype down on Taskbar.

Thanks for the additionl info on the command "netstat"
