Try turning off TCP header compression on the NetBlazer's (provided it
is on).  This has proven to be a problem with the TCP/IP stack being
used in the NetBlazers earlier, it will have problems with TCP data-
grams with IP options set, something that will happen between modern
(at least 4.4BSD-Lite based) TCP/IP stacks.
