Yes, that's a good point - a firewall could be closing a connection.
If it's the kind of app. that has to survive in such an environment, I
would recommend that they implement an application level keepalive
though - that won't be dependent upon the vagaries of the underlying
OS or local sys admin (who may have changed the kernel level TCP
keepalive settings without your knowing it).
