Hal,
	
	There have already been several postings to the list about port
6112.  26000 is also a game port.  It raised several flags for me as
well (looking like a port scan), because the Windows game client uses
steadily increasing port numbers as it goes along.  I got worried when I
saw a lot of traffic trying to access 2049/udp (NFS) from the net.
