hi Anton
yes, the Java classes are sent as they are (i.e. the Java bytecode, NOT source code) to the Collector and back. if they don't want the classes to leave the machine/network, they'd have to put collectors on those machines/in those networks.
opening the firewall only from agent -> collector -> server should be enough, as the TCP connections are always established in this direction.
hope this helps,
Christian
