Goal: Set up virtual box network, connecting 3 internal networks of VMs to public network via router VM.
- Set up 3 internal networks (red, blue, green) and two VMs (a, b) per internal network
- Set up router VM, add NIC per internal network
- Set up 4th router NIC to direct ethernet access of home network, without NAT or host-only networking
- Install DHCP server on router
- Configure routing to allow VMs to access each others' networks
- Configure NAT on router (SNAT) so VMs can reach internet, using either ISP DNS or google DNS (8.8.8.8)
- Block redNet access via iptables
- Block access by default via iptables, move to explicit white-listing only for allowing network access
- install recursive DNS server on router, update DHCP to use this DNS
- move DNS and DHCP servers to blueNet
