Comcast is now blocking ALL incoming traffic into your PC, so anything even thinking of running a server of any kind had better forget it. If you were running any kind of online radio station, as I was, a good alternative that works, and starting at a reasonable price is Live 365, atyou are a Comcast subscriber attempting to run your own streaming audio and want an alternative, Live365 is the way to go. Packages that include the ability to do live streaming from your computer start at $20 monthly. I have been trying to start my own online talk show and discovered that Comcast is now blocking all incoming traffic to customer computers. I did that by connecting back to my setup by using an open proxy server, and disovered that all incoming traffic is now blocked.
