could anyone explain me why I get different results when I doing nmap -sS <ip> from a remote site to my system and when I do nmap -sS localhost on my system?

You are running a packet filter, so you should know.

From remote site I get results with a closed tcp port 113, with nmap with localhost not.

"Not" what? "Not" closed, "not" opened? What does ´netstat -ltnp´ say?

And of course, why respond the system to tcp port 113, even if inetd is not startet?

Port 113 is the identd. It is not fired up by inetd in most cases.
