VMWare Workstation networking problem...

I got VMWare Workstation 6.5...

When i install a guest OS as VM, "sometimes" i couldn't use internet, although I configured the VM to use NAT and other options in VMWare, the guest OS didn't go to net...

Could some explain me briefly what NAT, Bridged Network and other networking terms in terms of VMWare Workstation with simple examples?

And why does this problem occur? (As i said in one guest OS, the problem doesn't occur and in another OS, the problem occurs)

For the record: I am using XPs, Windows 2000s as VMs...Some XP/2000s have this problem whereas others haven't got...

Best regards...

  • >> Could some explain me briefly what NAT, Bridged Network and other networking terms in terms of VMWare Workstation with simple examples?
    • This setting is used when you only have a single network card in your computer.  When bridged networking is selected, your computer's single NIC is used to share netowrk access between your guest OS's and your host.
  • The guest that is haveing trouble, check the following
    • Is there a gateway IP set?
    • How many NICs do you have in your host, one or more?
    • Is the Guest set to use bridged network or a specific NIC is you have a multi homed machine(more than one NIC)
    • I have found(in past situations), remving the NIC from the guest as re-adding it fixed a networking problem.

NAT: I have a single network card in your computer. You mean my host computer physically...Right?

>>When bridged networking is selected, your computer's single NIC is used to share netowrk access >>between your guest OS's and your host.

So, suppose my host machine has IP as ABC.ZXC.QWE.TYU, does the guest OS have the same IP configuration.

>>The guest that is haveing trouble, check the following
>>Is there a gateway IP set?
Host or guest?
If host, sometimes yes there is a gateway set and sometimes simply the host machine gets IP automatically...

>>How many NICs do you have in your host, one or more?
1

>>Is the Guest set to use bridged network or a specific NIC is you have a multi homed machine(more than one NIC)
>>To probe other network setting i set guest NAT, Bridged etc...(all other options), but no joy regarding internet...No more than 1 NIC...

>>I have found(in past situations), removing the NIC from the guest as re-adding it fixed a networking problem.
I will try it...

Best regards...

  • No, the Guest OS ALWAYS has its own IP.  If is only sharing the physical network connection to your LAN
>>If host, sometimes yes there is a gateway set and sometimes simply the host machine gets IP automatically...
  • Because the host OS has a dynamic IP, this will never affect the guest.  Once again, the guest is onyly sharing the physical network connection and not the IP of the host.
If you only have one NIC on your computer, this is how it should look.
