Scott,
I didn't find the random source ports in the range of 11000-11999 for DLSW
only a random source port that was not 2065 or 2067. I know H.245 uses
ports 11000-11999.
RfC 2166:
6.2.1.1 TCP Port Numbers
DLSws implementing these enhancements will use a TCP destination port
of 2067 (as opposed to RFC 1795 which uses 2065) for single session
TCP connections. The source port will be a random port number using
the established TCP norms which exclude the possibility of either
2065 or 2067.
