NAT Network Question

Post by MikeGreene »

I am taking a class which required me to setup 3 SEED VMs, specifically a DNS attack lab (http://www.cis.syr.edu/~wedu/seed/Labs_ ... DNS_Local/). I used 3 SEED VMs on a NAT network and all three VMs can ping each other and use the target DNS machine. However, running the attack tool netwag/netwox number 105 does not work from the attack system to the user system. I can initiate the attack locally on the user system and the result is as expected. I was wondering if this issue has something to do with VBox NAT Network. The host system is a Gentoo desktop running VBox 5.1.8.

If I were doing this I would not use nat network. Internal will act like a switch for the guests and keep the local lan and host out so they remain safe. So try intnet and see if it will work for you.

Okay, I will give that a try. I did switch all the VMs to NAT from NAT Network and when I started them all three came up with the same IP (see attached), is that normal?

Yes. VBox NAT is an isolation protocol. None of the guest or host can see them by default.
