Can somebody please point me to a documentation of the UTM network service architecure? What I am looking for is a description of the interaction of the UTM appliance, the Endpoint agents and the internet services provided by Sophos (e.g. broker) especially considering name resolution and IP addressing.
How does an endpoint agent know how it can connect to an UTM on the internal network (private zone and IP addresses) if the UTM is not acting as a default gateway?
How does the name resolution and connection to the UTM work if the endpoint agent moves to a public network? Is a split DNS setup required?
Does the name resolution involve a broker service from Sophos? How robust are these mechanisms against changes of the domain names?
Thank's a lot!
Martin
