That does NOT make it a security feature, more so as there are so many variants of NAT. NAT has some side effects that resemble security mechanisms commonly used at the network edge. While NAT can provide some protection it's not a firewall, for the same reason as above( when using NAT, inbound hosts can't connect unless portforwarding is enabled).
Incomming connections have to be routed with portforwarding as the host cannot know for what virtual machine the connection is meant. In the displayed file dialog, you can click Add to select any disk image file on your host disk. The NAT translates your virtual machines IPs to a single IP. Alternatively, click on the small folder icon next to the drop-down list. This means in your case that they will be directly connected to the network your host connects to, getting IP addresses from the DHCP server running on the network (which probably also gives your host its IP).īecause you would need to enable portforwarding on the NAT segment. With a bridged interface your virtual machines are directly connected to the network the network interface they are using is connected to.
The IP is assigned by a DHCP running on the host You can access the network because your host is doing Network Address Translation (if you don't know what that is What is strict, moderate and open NAT? ). Meaning your VMs are on a different subnet. With NAT the IPs of the virtual machines and the network your host is connecting to are separated.
