Help me connect between Linux and Windows

[dokota]

Hi all,

I created VirtualBox (3.2) and installed Oracle Linux version 5 update 5. My host machine is Windows XP SP3.

I installed Oracle Linux ok. But I have a problem is: I can ping to other Windows machines from Linux but from other Windows machines I can not ping to Linux.

When create VirtualBox, my Network adapter choosen NAT type. And enable DHCP (dynamic IP address)

I list some infomations from Linux:

If I use system-config-network to edit to static IP address, I can't ping to Windows machines. Plz help me.

[coopstah13]

you are using NAT, which means that your host is the router to your virtual network

if other machines are to ping this, you need to give them a route to that network, you can add routes to network adapters in their properties

otherwise, they have no idea how to get to the virtual machine network

[dokota]

Thanks coopstah13 for reply,

As your guide, I use command system-config-network to edit network configuration by GUI.
From Network Configuration GUI, I choosen Edit and navigate Route tab then Add ... but you can said about some informations that I have to add ? I used (from Windows XP network configution):

+ Address: ??? <-- I must create a valid IP address ???
+ Subnet mask: 255.255.255.0
+ Gateway: 192.168.1.11

Can you help me about it ? thanks.

[coopstah13]

no, you have misunderstood

the windows machines that you are trying to ping from, to the linux virtualbox must have a route added

Change the adapter mode to "Bridged" (see attached image), this would put the guest VM on the same network as the host. It would give the linux machine (guest) an 192.168.1.x IP
