下面是我当前的设置，主要的以太网连接配置了静态 IP，并且工作正常。另外两个接口使用 DHCP 连接到不同的 Android 热点。我还配置了路由，以便每个接口都可以独立接收/发送流量
下面是我的完整工作/etc/network/interfaces文件
root@poweredge:/etc/network# cat interfaces

# and how to activate them. For more information, see interfaces(5).

post-up ip rule add from 192.168.43.209 lookup wlx74da388c32c7
我已使用以下命令确认每个接口都独立工作
curl --interface wlx74da388c32c7 ifconfig.co
curl --interface wlx74da388c32d0 ifconfig.co
curl --interface enp1s0 ifconfig.co
每个curl 命令都按预期显示连接的公共IP 地址。这正是我希望事情顺利进行的方式。
但是，当我在其中一个无线接口上设置静态 IP 时，我遇到了问题。例如，当我将接口更改wlx74da388c32c7为静态 IP 时，如下所示
auto wlx74da388c32c7
iface wlx74da388c32c7 inet static
address 192.168.43.100
netmast 255.255.255.0

post-up ip rule add from 192.168.43.100 lookup wlx74da388c32c7
当我尝试使用任何界面获取页面时，curl 就会挂起。

我的ip route list何时使用 DHCP
root@poweredge:~# ip route list
default via 192.168.1.1 dev enp1s0 onlink
172.16.11.0/24 dev wlx74da388c32d0 proto kernel scope link src 172.16.11.107

192.168.43.0/24 dev wlx74da388c32c7 proto kernel scope link src 192.168.43.209
我的ip rule list何时使用 DHCP
root@poweredge:~# ip rule list
0: from all lookup local
32764: from 192.168.43.209 lookup wlx74da388c32c7
32765: from 172.16.11.107 lookup wlx74da388c32d0
32766: from all lookup main
32767: from all lookup default
有人知道我做错了什么吗？
答案1
在你的输出中IP规则列表你有ip192.168.43.209该 IP 不匹配192.168.43.100。
为了简化您的路由表，您可以更改为：
post-up ip rule add from 192.168.43.0/24 lookup wlx74da388c32c7
