VLAN 인터페이스 추가, 기본 호스트에 연결할 수 없음

네트워크 에 Ubuntu를 실행하는 VM 서버가 있습니다 192.168.1.0/24. 내 네트워크의 DMZ에 있을 VM에 사용될 VLAN 태그가 지정된 하위 인터페이스를 추가하려고 합니다. 구성 sudo vconfig add enp2s0 30에서 다음을 사용 하여 먼저 하위 인터페이스를 추가했습니다./etc/network/interfaces

# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo br0
auto enp1s0
iface lo inet loopback

###bridge interfae for vm's
iface br0 inet dhcp
    bridge_ports    enp2s0
    bridge_stp      off
    bridge_maxwait  0
    bridge_fd       0
    dns-nameservers 192.168.1.1
    dns-nameservers 8.8.8.8
    gateway 192.168.1.1

###power-fail backup NIC
iface enp1s0 inet static
  address 192.168.40.2
  network 192.168.40.0
  netmask 255.255.255.0

#suberinterface for VLAN segregated VM's
auto enp2s0.30
iface enp2s0.30 inet dhcp
    vlan-raw-device enp2s0

###network shim for dockers
auto macvlan0
iface macvlan0 inet static
    pre-up ip link add link br0 name macvlan0 type macvlan mode bridge
    address 192.168.1.42
    network 192.168.1.0
    netmask 255.255.255.0

###routes for dockers
post-up route add -host 192.168.1.16 dev macvlan0
post-up route add -host 192.168.1.43 dev macvlan0

여기 나의 ip route:

default via 192.168.1.1 dev br0 
192.168.1.0/24 dev br0 proto kernel scope link src 192.168.1.41 
192.168.1.0/24 dev macvlan0 proto kernel scope link src 192.168.1.42

192.168.40.0/24 dev enp1s0 proto kernel scope link src 192.168.40.2

그리고 여기 내 기존이 있습니다ip addr

네트워크 서비스를 재설정한 후 인터페이스가 나타나고 IP 주소를 가져옵니다. 그러나 이제 상위 인터페이스에서 실행 중인 어떤 VM에도 연결할 수 없습니다 enp2s0. 상위 인터페이스에 일부 라우팅을 추가해야 합니까 enp2s0? 이 서버에는 두 개의 NIC가 있습니다. 기본 NIC는 입니다 enp2s0. Enp1s0정전 시 UPS와 통신하기 위한 백업 NIC 역할을 합니다.
