Hi,
I have an client-server application that is running over a VPN to a customer site. The client machine is in my office and the server is located behind the customers VPN and firewall.
When I log into the application I can bring up http based graphs and reports. However, when I run java based applications they are not working and say they cannot connect to server. In the customer site they are able to run these applications from their desktops. This would imply that the issue I'm experiencing are caused by either the customers VPN or Firewall.
Basically we use ndd on the server to set the port range for tcp and udp. We have asked the customer to open this range on their firewall and they have said they have done this. However, when we try to run our Java based applications, the customer's IT person says that they see attempted UDP connections for ports outside of our specified range. Naturally this gets denied.
We have done extensive testing in house with a Firewall and have found that our application will always go to ports in the range specified.
What is happening here?
Does anyone have any idea how I can check what is going on and how to correct it?
Thanks,
Tom
