How to access a server http port 80 with port forwarding behind a router but require a password

[Brian Cluff]

If you just don't want you web server to show up at all, I think that I 
would just use port knocking.  This won't truly secure your information 
as someone would be able to figure out your knock sequence by just 
listening in on the traffic goinging to your machine, but if your after 
hiding it more than securing it, it's a great way to go, and most likely 
nobody will be listing anyway.
