Tom, Thanks. I'll pursue this avenue and let you all know how it goes.
Did Stefaan post a reply? Yours is the first reply I received. I wonder if I'm 
missing posts...

Hi John,

As Stefaan said, you can't and don't really want to do this with
protocol rules. Sounds like your app works like RPC. The best solution
is an application filter. If you have a C++ guy on staff, maybe he can
study the SDK and fry you up an app filter.

HTH,
Tom

Hasn't anybody else had the need to open a range of ports through ISA? I
did not think this would be that uncommon.

Is there any way to open a range of ports with one definition?
I need to publish a server and allow connections from the outside on a
range of 1000 contiguous ports. I have tried creating a protocol
definition with the first port as primary and the rest 999 as secondary
but it does not work. Creating 5 individual protocol defs and 5
individual SPRs works but only allows 4 simultaneous connections. This
server is running a complex application. The external clients always
initiate the connection on one fixed port. The server application sends
back to the client a random reply port within a predefined range of 999
ports (it's kind like RPC). To make matters worse we are currently
hosting 3 of these servers for 3 different customers and more are on the
way...
There is just got to be a way to do this without having to create 1000s
of protocol defs and 1000s of SPRs!!!!
