Quick answer: money. I'll take any donations for the $3000 hardware-based
firewall that's needed so I can replace the free software-based one that I
have been using.

I am not sure what the protocol is for the person that runs the UW license
server (I refer to the gis.washington.edu server, which I think is
campus-wide and not a personal one), but why would the administrator use a
stealth firewall on that one?
A properly functioning firewall on a machine that serves the public which
may refuse connections on a default port should message back to whomever
made the request with a refusal. Using stealth methodologies on standard
ports that are meant to be open creates these slowdowns that many
experience. Perhaps this practice should change, at least for the
University-wide license server. TCP timeouts are by definition set to a very
long duration to support temporary network outages; ESRI may handle this
differently than the TCP protocol, but relying on how ESRI defines behavior
and not following standards is perhaps not an ideal solution.
Then again, I am just really happy someone runs the license server for all
of us, and I am more than willing to work around any restrictions that
person/entity sets for us.
