Hello,

I have client-service application where the client invokes the service
and subscribes for notifications of a resource changes. The service
does some computations and puts the results in the resource; the
client is then notified of the resource modification and it retrieves
the results from the resource.

The servers where the service is exposed resides in a DMZ, where each
server has both an own local IP address and an own external IP address
associated with an own host name.

The application works smoothly when the client runs on a computer
connected on the same local network where the servers resides.

When the client runs on a computer residing outside the servers LAN,
the client succeeds only to invoke the service and to subscribe for
the resource changes notification: the service ends the computation
without errors but then the client does not receive any notification
and waits indefinitely.

Does anybody know what could be the problem?
