通过 LAN 将虚拟机连接到具有 WAN 的虚拟机

Question

使用 Esxi 6.7，我有两个客户机（每个客户机上都有 Debian 10）。Guest-1（VM-1）配置了这样的公共 IP，并连接到 WAN（互联网）：

sudo nano /etc/network/interfaces

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo iface lo inet loopback


# The primary network interface
allow-hotplug ens192
iface ens192 inet static
    address xx.211.44.103/32
    netmask 255.255.255.0
    gateway yy.27.36.113
    dns-nameservers 8.8.8.8

Vm-1 已连接到互联网，没有问题。我需要在机器 Vm-1 和 Vm-2 之间配置本地网络，请告诉我如何为 Vm-1 添加辅助内部 IP并为 Vm-2 添加yy.27.36.151主内部 IP 。yy.27.36.152

我尝试过这个：在 Vm-1 中：

# The secondary network interface
allow-hotplug ens193
iface ens193 inet static
     address yy.27.36.151
     netmask 255.255.255.0
     gateway yy.27.36.113
     dns-nameservers 8.8.8.8

和 Vm-2：

# The primary network interface
allow-hotplug ens193
iface ens193 inet static
     address yy.27.36.152
     netmask 255.255.255.0
     gateway yy.27.36.113
     dns-nameservers 8.8.8.8

问题是辅助接口名称应该是什么？ens193以及如何配置每台机器？
