Confused about some port scan results.

Hi guys, I have a couple of quick questions. I'm not really a networking expert; I have a piece of hardware on my LAN and I'm trying to do a UDP port scan on ports 6000 to 6500, and I've just downloaded nmap (4.65, Windows XP SP2, no software firewalls) to do that. The results I get are: $ nmap -sU -r -p6000-6500 192.168.2.200 Starting Nmap 4.65 ( http://nmap.org ) at 2008-06-25 23:23 Eastern Daylight Time All 501 scanned ports on 192.168.2.200 are open|filtered MAC Address: 00:0A:C5:22:63:B6 (...) Nmap done: 1 IP address (1 host up) scanned in 12.735 seconds 1. I'm using the correct command line options, right (UDP scan, in order, 6000 to 6500, of 192.168.2.200)? 2. I happen to know that the device only watches for data on port 6300. Why does it say all 501 ports are open/filtered? 3. What does "open/filtered" mean? Actually what does "filtered" mean? When I think "filtered" I think "blocked" which is sort of the opposite of open, but I'm pretty sure nmap isn't trying to tell me that "all 501 ports are either open or they aren't", lol. Thanks!
