Yeah i've enable the SVM mode. Currently going for the Server Eval x64 20xx for testing. It could expire but should not be a problem for now. I will note this and see if there is any way I can test my other system with the other version.

Windows firewall yes, but it really slow and not always responding right to my block or accept request... strange behavior on the network as well. Like it is being bypassed for some reason by localhost or not hitting the firewall at all.
Any idea for a VM based firewall... and if there is, how would that be sec technical? Would it be an issue for it being on the same Hypervisor or not.

ISP locked the Routers for using a Router that is bought by myself. So no own router yet and my experience as Network Engineer says that it is better to have a "appliance" separate from the router.
