Isolation
On hosts where cloned, copied, refreshed, or renamed instances are running, all outgoing transmission control protocol (TCP) connections are blocked to isolate the target system from its source system. You define which TCP connections are allowed on the hosts. By default, all connections needed within the target system are allowed.
Prerequisites
-
Make sure that you allow all ports for outgoing connections, which must be reachable from all cloned, copied, refreshed, or renamed systems.
-
Make sure that you block all ports for outgoing connections, which must not be reachable from all cloned, copied, refreshed, or renamed systems.
