I am a web developer running a demo server at home. My site is accessible from Atlanta as well as via my local cellular network. However, both a webserver I have in Utah and a webserver of a service I need to interact with that is in California are unable to connect to my server. Communication goes through if I initiate the connection to the webservers. When I do a traceroute, the route ends at a Comcast-owned IP address. I am a Comcast customer, so I call their support line. After 1.5 hours of being passed up to the next tier of support, I finally get a ticket number and a promise of a callback. Callback came quickly, but merely told me I would have to email firstname.lastname@example.org as they are the only entity who could adjust the filters. I have send email@example.com two emails with the IP addresses for my local connection, the two webservers, and the router that is blocking the traffic, but I have not heard back. Does anyone know another way to get this traffic unblocked so I can receive the traffic I need to receive?

The proper way to solve this problem is to host your demo website somewhere that is designed to host websites. Your home cable connection is not designed for this purpose and trying to host a website, even a demo website, from home will only cause you grief.
A free-tier EC2 instance from Amazon can be created from scratch in about 30 minutes, which is about 1/3rd the time you spent on the phone to the Comcast helpdesk.
Many other VPS and shared hosting providers come in at the $2 - $5 per month price range.
As for your actual question, how to get Comcast to allow port 80 traffic to reach your home connection, you have already done everything that you can do. Now you wait to see if they actually do it. While you're waiting, you might want to have a look at one of the options above.
