我有一台专用服务器，正在尝试创建 NAT。我的虚拟主机是 LinuX 容器，我只有一个公共 IP 地址，我正在尝试通过 LXC 连接到互联网。
在我的主机上，我可以访问互联网的默认接口是 eno1，并且我在其上创建了一个桥接器：
auto lxc-nat-bridge
iface lxc-nat-bridge inet static
bridge_ports none
bridge_fd 0
bridge_stp off
address 192.168.1.1
netmask 255.255.255.0
post-up echo 1 > /proc/sys/net/ipv4/ip_forward
这是我的 LXC 的网络配置：
# Network configuration
lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = lxc-nat-bridge
lxc.network.ipv4 = 192.168.1.2/24
lxc.network.ipv4.gateway = 192.168.1.1
lxc.network.veth.pair = vethWeb
然后我输入了这个 iptables 规则来创建一个伪装：
iptables -t nat -A POSTROUTING -s 192.168.1.0/24 -o eno1 -j MASQUERADE
当我启动容器时，我可以从主机 ping 它，但是当我加入容器并执行 apt update 时（这是我用来检查互联网访问的命令，因为没有安装 ping）：
root@web_container:/# apt update
Err:1 http://deb.debian.org/debian stretch InRelease
Temporary failure resolving 'deb.debian.org'
Err:2 http://security.debian.org stretch/updates InRelease

root@web_container:/#
它不起作用:(
以下是在容器中执行的 ifconfig：
root@web_container:/# /sbin/ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
