Hi Stuart,
It may in fact be that the app requires secondary connections. I can't
vouch for the authors of the app, but it would make more sense to allow
a single inbound port that the client and server can use to negotiate a
secondary connection. Then the external client connects to the negotiate
port designated as a secondary connection.
But I'm not a coder so I can't imagine what goes on in these guys heads.
Maybe they think its more secure to allow hundreds of primary
connections to their app?
Thanks!
Tom

It's a progress application with the database, nameserver, broker, &
agents (it's the agents that uses many ports).
From what I understand, and I'm no progress expert, when a new
connection is made to the database (to query, insert whatever) via
webspeed it picks a port from a certain range and uses that port to
communicate for the duration of that session.
We have been told by the authors that the range is user definable but
given the traffic levels we're expecting that it would impact
performance if we were to shorten the pool to a more manageable length.
Might be a pain in the ar*e at the moment but from what we've seen at
other law firms it is an impressive piece of software.

Hi Stuart,
I'm curious as to what application requires such as large number of
primary connections.
Thanks!

Maybe this would be something MS should add? As it means that I have to
now create 100 different protocol definitions. I know you can do this
on a PIX (not sure about other firewalls)
Anyways off to my isa server
Thanks Jim

Not if you're referring to a collection of primary connections. What you
need to do in this caase is create each individual protocol definition.
If the protocol uses a single primary port and many secondary ports,
then yes; a single definition can do the job.

Is it possible to create a protocol definition that contains a range of
ports?
lets say I wanted to publish a server on the following TCP ports 3202 to
3302 would I need to create 100 different protocol definitions?
