One thing to remember is Bridged mode will mean any network calls bypass your VPN and reveal your IP address and activity on the Internet with no privacy. Add a comment. Active Oldest Votes. Host-only only permits network operations with the Host OS.

Likely in a completely different range, and not routable on the current LAN. You will see a virtual adapter on the host OS which will have an address in the same range.
Yeap, you got it. The description of host-only networking in this answer isn't quite accurate and implies that the VM is accessible only by the host OS. That's why, by default, a machine behind a NAT device is "protected". Bridged mode acts just like the interface you're bridging with is now a switch and the VM is plugged into a port on it. Everything acts the same as if it were another regular machine attached to that network.
Meaning your VMs are on a different subnet. 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? With a bridged interface your virtual machines are directly connected to the network the network interface they are using is connected to.
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.
Because you would need to enable portforwarding on the NAT segment. Incomming connections have to be routed with portforwarding as the host cannot know for what virtual machine the connection is meant. 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. NAT has some side effects that resemble security mechanisms commonly used at the network edge.
Bridged connections are just that, essentially a virtual switch is connected between the VM and your physical network connection. Since the host computer actually sees IP packets and TCP datagrams, it can filter or otherwise affect the traffic. When the VM is using bridged mode, it's connecting to the network via the host at a lower level Layer 2 of the OSI model. The host machine still sees the traffic, but only at the Ethernet frame level.

In this diagram, the vertical line next to the firewall represents the production network and you can see that There is also a virtual host with three virtual machines running inside it.
The big red circle represents the virtual adapter to which NAT-based virtual machines connect If you didn't create them the first time vmware-config. Accessibility from network Same as a physical host Hides behind NAT, so port forwarding on the VMware host required if external access required Not accessible from external network unless routed via another VM with access to both external network and the same host-only network Use cases An always-on server hosted on VMware, or a virtual router or firewall VMs intended for testing, or cases when the amount of IP addresses in the external network is limited.
VMs intended for testing with no need to access the network, or VMs which will be protected by a firewall in another VM. Other Known to have problems with some wireless chipsets especially with Linux, also with Windows Vista.
