Setup a dhcp server config for the basics:
  1) local subnet
  2) create static host mapping for the fresh-install host
  3) set ttl for leases super low (30 seconds? 15?)
  4) start/restart dhcp server

Set ip_forwarding/ip.forwarding in /etc/sysctl.conf + hand set in /proc.
# Uncomment the next line to enable packet forwarding for IPv4
