Well, after configuring everything on my computer, I kept wondering why I wasn’t able to hit my web server from work. At home, I had no problem accessing it via the domain name. Then it occured to me that that Comcast must be blocking incoming port 80. I downloaded the port scanning software below and verified that port 80 is indeed blocked. Hopefully, this will just be a minor setback.
