Hi,

We are using the Push Notification feature to Send messages to our logged in clients.

Everything works correctly when the users are on the network, however when the user is connected via VPN errors occur.
I have figured out that the port number that is being used for the seperate notification channel is being blocked.

When using NETSTAT or a network protocol analyser I can see the used port number on the server.
The problem is that this server port number changes every time I log in.

Is there a way to specify the port the server must use?
(similar to this in the app.config: <notificationService clientPort="9012"/>)

I noticed in a past post that there was mention of a server port.

Alternatively, would changing to the net.tcp bindings have the same problem?

Thanks

Hi Cornholio,
Unfortunatelly, the serverPort attribute of notificationService is not present in DevForce2010.
However, using net.tcp might solve the issue as you won't need to set a separate port for the notificationService.
