Network configuration
From Luna Node
Normally, your VM will automatically acquire its IP address via DHCP. However, if needed, you can manually configure the network. Suppose your private IP address is 172.20.5.5 (your external IP doesn't need to be configured on VM); then use these settings:
IP: 172.20.5.5 Subnet mask: 255.255.0.0 Subnet: 172.20.0.0/16 Gateway: 172.20.0.1 Broadcast: 172.20.255.255
