Hi there,

you are a bit confusing here :-).
You say you want to offer ftp and http services, but you want your system to appear closed to scanners?
As far as I know, you can not do what you want to do.

A scanner is just doing the same as any regular webbrowser does when it connects to a webserver, so to appear closed to intruders, you must not offer any services.

Best regards,
Ørjan Sandland

can't you modify the PSD to lock the address for a while?

So if someone begins scanning random ports you lock them off? Well thats a good idea period who cares about if they see port 80 and port 21 first because hopefully the firewall will blacklist their ip.
