添加了vlan接口，主主机无法访问

我在网络上有一台运行 Ubuntu 的 VM 服务器192.168.1.0/24。我试图添加一个 vlan 标记的子接口，该子接口将用于位于我网络上 DMZ 中的 VM。我首先添加了子接口，然后在配置中添加了sudo vconfig add enp2s0 30以下内容/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

这是我的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 
192.168.1.16 dev macvlan0 scope link 
192.168.1.43 dev macvlan0 scope link 
192.168.30.0/24 dev enp2s0.30 proto kernel scope link src 192.168.30.2 
192.168.40.0/24 dev enp1s0 proto kernel scope link src 192.168.40.2

这是我现有的ip addr

重置网络服务后，接口会启动并获取 IP 地址。但是，现在我无法访问在父接口上运行的任何虚拟机enp2s0。我需要向父接口添加一些路由吗enp2s0？此服务器有两个 NIC。主 NIC 是enp2s0。Enp1s0用作备用 NIC，以便在断电时与 UPS 通信。
