Monitoring Over Firewall

Hi,

Does any one know how to over come the problem of "monitoring the load generators over firewall" ?

We are able to use these machines for load generation, but are not able to monitor the measurements of these machines. When tried to add these machines to the windows resources, we were getting the error "Monitor name :Windows Resources. Cannot connect to machine stresstestxp6:62043.Reason: The network path was not found."

Also note that, we are able to ping/telnet the LG from the controller, but not the vice versa

Is there any router settings to be made or any other configuration has to be done?

The client is interested in using the existing UNIX / Windows Monitors to get the data rather than to go for Sitescope. We are able to add the LG which are located within the network, but we are not able to add the LG which are located outside the network. This is where we are stuck.

The point is that till now we are using these LGs for our different Load Tests. Now, the client wants the monitor the resource usage of these machines too. This is were we are stuck now.

The problem which we are facing is that there is only one way communication. That is, when we try to ping or use telnet from the controller to the LG, we are getting the response, but when we try the same from the LG, we are not getting the response from the controller.
