I believe fpe communicates over an additional port besides 80 although I can't remember what the port is off the top of my head. Google fpe ports and you should find it. Although if you really did set your computer in the dmz then ports shouldn't be an issue. But you shouldn't have to do anything with remote administration in order to check port 80
I'd also suggest dumping front page unless you are just doing these did as a hobby. The html front page generates is pretty outdated by today's standards. You could try using expression web which is a step up from front page.
