You needn't set local port, what you should do is deploying a Silverlight socket policy file.
Right. We did that and it is working great for the Silverlight applications.
Where we are having problems is connecting from our Windows Forms Applications. And only on *some* of those installs.
What we are thinking is there are some local policies locking down *outgoing* ports. So we want to isolate those instances and find Ports availble thru whatever local Workstation/Client side policies.
This may not be where the problem is but because of stringent *locked down* client policies it is where we are currently looking.
That's why I was asking if we could specify the Port being use at the *Client* side.
