IP Addresses of Relay and Block Producer Nodes in VirtualBox

Hello. I am following the Stake Pool Course. So far so good. But today, I have a road block. I am now in the part where I am changing the topology files so that Relay nodes talks to BP node and other relay nodes. Also, BP node should only talk to my Relay node. I am doing all of this in VirtualBox. I was looking for the IP addresses of my nodes but but found out that they are using the same IP address ( How did you guys went ahead with this? I mean in my topology files, I cannot declare both relay and BP nodes to have the same IP obviously.

This solved my issue:

  1. In VirtualBox control panel go to File → Preferences → Network
  2. Select NAT Networks tab, create a new “NatNetwork” by clicking + button at side and press OK.
  3. Now select each VM go to Settings → Network
  4. In Attached to: option choose NAT Network and select “NatNetwork” and press OK.
  5. Restart all the VMs.
  6. Now VMs have different network address.

NAT adds overhead. Most routers are capable of guest/private LANs. You can create one and dedicate it to your vms over the same nic as your host. Routers are different, so Google is your friend. :slight_smile:
