BO2k Port?

Howdy List,
  Doing an audit on a gov agency with a Raptor Firewall.  I was shocked to
see nmap repeatedly reporting 31335 and 31337 UDP open on the firewall.  I'm
told by my firewall guys that Raptors and VelociRaptors install with all
ports closed and ports have to be specifically opened to allow traffic.  I
can't imagine the person that installed this firewall would allow those
ports.

   I haven't been able to connect with my BO2k consolde and am beginning to
wonder if this is a false positive.  I've seen Raptor Firewalls report open
ports when they in fact are not and am wondering if anyone has advice on
these high ports.
