Juan, 

I believe this link may provide some insight: 

http://lists.debian.org/debian-user/2002/06/msg02649.html

An excerpt from the above quoted link: 

"nmap labels a port as "filtered" if it does not receive either a
SYN-ACK or a RST in response to a SYN packet...."

Hope this is of assistance.

Josh
