Bridged vs NAT connections

  Bridged vs NAT connections At some point, we might all have deployed virtual machines using different hypervisors, be it Virtual Box, VMWare Player, etc. on our computers.   After installing the VM, we are usually provided with two network connectivity options: NAT or Bridged connection type.   Today we are going to look into the difference between the two network connection types. Let understand it with a below network diagram: Network Address Translation (NAT): When a VM is connected with NAT connection and network traffic is going out, the NAT device/adapter translates the address of VM to that of the host machine before packets are forwarded to external network. External world is not aware of the actual Virtual Machine, it will interface with Host machine. This is particularly useful when limited set of IP addresses are available in an organization.   The reverse happens when packets are received for the VM from external network (or Internet). In this case NAT ...
