I don't claim to be a firewall expert by any stretch, but just some common
TCP knowledge and your description would suggest that the port that it is
connecting on is open (1494), but the return port is not (random). I know
that some how firewalls can be configured in different ways to either allow
or not allow return traffic.
For instance, I have a connection to a Citrix server on port 1494 right now,
but my local port is 2849. It seems that maybe the Citrix server isn't
being allowed to talk back to port 2849.
Following Ron's suggestion, watch the firewall logs to see what ports are
being blocked and how.

Hey Ron,
No, it's definitely udp. Pretty wacky.

You sure you are still using UDP? Might be a silly question. But when it
fails I would just watch the logs and see what port it really fails on.

Hi all,
=3D20
I've got a problem. Who knew? ;-)
=3D20
Anyways... a client of ours has a business partner that connects to a
published application via the Program Neighborhood client (7). When they
put the server name into the Server Locator list, they still cannot
browse the published applications. We have verified 1494 tcp and 1604
udp are open and accessible by the client. The only thing we have been
able to come up with is that it is something with the Proxy Server. If
the Security engineer on their side sets it to "Unlimited Access", then
it works just fine... however, specifying those two standard ports alone
does not seem to do the trick.
=3D20
Has anyone ever run across something like this, and if so... how did you
solve it?
=3D20
Any help is appreciated.
