Network Setting

---

Management(VMnet18)

- NAT

- 192.168.2.0/24 : 192.168.2.10 ~ 192.168.2.20

- DHCP

Provider(VMnet18)

- NAT

- 192.168.2.0/24 : 192.168.2.50 ~ 192.168.2.254

- NO-DHCP

Self-Service (가상..)

--dns-nameserver 8.8.4.4 --gateway 172.16.1.1 \
	--subnet-range 172.16.1.0/24 selfservice

사실 Management Network는 내부 관리를 위한 네트워크이지만, 설치할 땐 인터넷이 필요하므로 NAT로 설정함.

Provider Network의 경우 외부에 인스턴스 서비스를 제공해야 하기 때문에 NAT를 쪼개서 할당함
