Guest VM as firewall for other Guest VM

са_никуз

Maybe you can help me a bit. I am new to VM player.. I have Host - win 7 and two Guests on VM player. Kali Linux and Windows xp. I have troubles with setting network connections. Task is to create firewall on Linux machine for windows xp machine. So I cannot understand how to get internet working on Windows XP through Linux machine. I have selected for Linux VM NAT connection for first adapter and host-only as second. (Internet works fine on Linux). On windows VM I have selected only one adaptor as host-only. And… stopped on this step.. What should be done next? I am I doing this right? As I understand host-only is just for internal network between two guests.. Thank you a lot

Your assumption of a "host-only" network is correct, but that network is also visible to your host PC. However, if you create a custom network of adapters facing inward on all three computers, you can have more complete control over it. But of course you have to set up a DHCP server or manually set the IP address.

Now all you need to do is get the IP of the inside interface on the linux machine and set it as the gateway for the two windows machines.

After that, you want to enable IP forwarding on the Linux machine, and then set up the NAT firewall on the Linux machine .

After doing all this, set the NAT interface you chose on the linux box to be bridged, which will allow it to get the actual IP address and reduce the chance of confusion.
