Hi, I just installed Windows 8.1 Pro as a VM using VMware workstation 10.  I have other guests OSes and they worked fine.  However, this Win8 VM IP addr is always 192.168.233.x when I use NAT.
When I switched from NAT ot bridged mode, I won't get any IP address.

When using NAT Mode, the VMware Workstation 10 Internal NAT DHCP Server issues an IP Address.

When using Bridged Mode, the VM Network Interface is linked or bridged to your physical network interface in your host, and will then rely on getting an IP Address from you Local Area Network.

How does your Windows 8.1 Pro computer get an IP Address?

Do you have a DHCP Server, or function, service running on a computer, server, or router?

I have three other VMs running. They are two Win2012 servers and one Win7 home edition setup for bridged mode and getting their IPs from the home router.

The laptop is connected wirelessly to my home router.  

Shouldn't the Win8 vm be receiving the IP 192.168.0.x from my router?

Are these three VMs also running on the laptop?

The VM should get an IP Address from the router?

Yes, the three VMs are running on the same laptop and they are getting valid IP addr (192.168.0.x)  from the router.

Can you try

1. toggling the interface from NAT to Bridged.
2. remove the network interface and specify Bridged.
3. If you manually assign an IP Address to the VM in Bridged Mode can you ping your router IP Address?
4. Router not run out of IP Addresses?

Already toggled the interface from NAT to Bridged.  Removed the current interface and add a new interface with NAT or Bridged mode.  Still the same problem.

I manually assigned an IP addr but cannot ping the router, but when I left it alone and received the IP 192.168.233.x I can ping the router and access the internet.  Weird.

So why did the interface received the IP 192.168.233.x ?

Router not ran out of IP addresses.

** pls note that when I configured the interface as NAT, I received the IP addr 192.168.233.x and not 192.168.0.x .  I will have internet access but

Yes, that's what NAT does, VMware Workstation 10 has an Internal DHCP server on NAT Network 192.168.233.x.

So when you select NAT, it gets a DHCP IP Address from VMware Workstation.

This is NATTed to your physical network, and hence NATed to the Internet.

Do you understand this?

NAT, Bridged and Host only a very different network functions.

What IP Addresses are the other VMs receiving?

I didn't check the other VM cause they were setup with static IP addr.

I now understand when you said VMware Workstation 10 has an internal DHCP server that uses the 192.168.233.x  ips.

When you said "this is NATTED to your physical network and hence NATed to the Internet", do you mean there is an internal routing going on in VMware Workstation 10?

Correct, NaT - network address translation, between internal LAN and external LAN (you LAN connected to physical network interface).

What is the NAT network.

This is the same function your Internet Router performs, because it has a single IP Address on the internet, to multiple IP Addresses in your LAN.

NAT is performed.

for the following reason:

Now that I know Workstation 10 has an internal DHCP that uses the 192.168.233.x network, it makes more sense.  Thank you.
