我需要一些帮助，因为我快要疯了，想弄清楚这一点。我一直在使用本指南运行带有拆分隧道设置的静态网络：https://www.htpcguides.com/force-torrent-traffic-vpn-split-tunnel-debian-8-ubuntu-16-04/这个设置已经工作了一段时间（大约 3 个月），直到我用一个新的交换机替换了一个交换机并添加了一些新电缆。我不确定这对接口有什么影响，但出于某种原因，它不想再加载接口了。我在下面提供了一些信息以提供帮助。
这是我当前的 /etc/network/interfaces 文件：
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eno1
iface eno1 inet static
address 192.168.0.30
netmask 255.255.255.0
gateway 192.168.0.1
dns-nameserver 8.8.8.8 8.8.4.4
# Secondary NIC Interface
auto eno2
iface eno2 inet static
address 192.168.0.31
netmask 255.255.255.0
# Auto IPV6
iface eno1 inet6 auto
iface eno2 inet6 auto
这是我从 ifconfig 获得的打印输出：
journey@ubuntu1:~$ ifconfig -a

现在这是我的 ip addr 输出：

到目前为止，我无法 ping 通 Google 或网关 (192.168.0.1)。100% 数据包丢失。我还看到 VPN 未连接，并且由于无法提升网络接口，导致启动时间额外增加 5 分钟。
我还想指出，我有另一台服务器运行在同一台交换机上，具有几乎相同的接口文件，并且运行良好（是的，它也以完全相同的方式设置了拆分 VPN）。请在此处查看该接口文件（请注意，这是一台 Ubuntu 16.04 服务器，而不是 16.10，并且是仅配置了拆分隧道的全新安装）：
# The loopback network interface

iface lo inet loopback
# The primary network interface

任何可以补充的见解都将不胜感激，因为我不知道下一步该尝试什么。谢谢！
