As for "UDP wide open": Did you consider the fact that every filtered UDP port is reported as "open" by an nmap scan?

nmap will report everything as "open" for which it doesn't receive an explicit ICMP_PORT_UNREACH. Unless you've configured your firewall to REJECT instead of DROP, nmap will not see any responses at all.
