我正在尝试通过以下两个接口（具有静态 IP）访问 Raspberry Pi 上的 Web 服务（端口 8080）：
- 以太网（eth0、172.22.0.99，连接到 Netgear 路由器）。
- Wi-Fi（wlan0、172.24.1.1，提供接入点）。
目前，只有连接到 eth0 并获得 IP 地址 172.22.0.x 才能访问 Web 服务。
如果我连接到 wlan0 上的 Wi-Fi 接入点，那么我正确地获取了 IP 地址 172.24.1.x，因此 SSH 可以工作，但 Web 服务无法访问（两者http://172.22.0.99:8080和http://172.24.1.1:8080）。
我一直在使用 Windows 10 笔记本电脑测试上述内容。实际问题是我有许多 Arduino 可以连接到 Pi 的 Wi-Fi 接入点 (wlan0)，但无法访问 Pi 的 Web 服务。因此，我目前必须通过 Netgear 路由器（即 Pi 的 eth0）连接它们。这就是我试图避免的。
另外：Pi 也在运行：
- OpenVPN，因此 eth0 被桥接（br0、tap0）。
- Wi-Fi 嗅探器（wlan1alfa、renameX）。
- 172.22.0.100/102/106/113 Arduino 工作示例
各种输出：
Windows 10 笔记本电脑连接到 Pi 的 Wi-Fi 接入点时：

编辑 2：配置更改后，Domoticz Web 服务器现在正在侦听 0.0.0.0:8080，但仍然如上所示失败。
$ sudo netstat -taupen | sudo netstat -taupen grep 多莫蒂兹

答案1
问题解决了！我只执行了以下单个刷新命令：
sudo iptables -F
因此，具体而言，我没有刷新所有 iptables 规则，例如。 NAT。
所以我有一堆 PREROUTING 和 POSTROUTING 重复项：
$ sudo iptables -t nat -L
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
DNAT tcp -- anywhere anywhere tcp dpt:http-alt to:192.168.0.99:8080
DNAT tcp -- anywhere anywhere tcp dpt:http-alt to:192.168.0.99:8080
DNAT tcp -- anywhere anywhere tcp dpt:http-alt to:192.168.0.99:8080

Chain INPUT (policy ACCEPT)

Chain POSTROUTING (policy ACCEPT)

MASQUERADE all -- anywhere anywhere

一旦我在创建规则之前开始使用以下内容，它就起作用了（没有其他变化）：
sudo iptables -F
sudo iptables -X
sudo iptables -t nat -F
sudo iptables -t nat -X
sudo iptables -t mangle -F
sudo iptables -t mangle -X
sudo ipset flush
sudo ipset destroy
sudo ipset list
显然我也应该这样做：
sudo iptables -t raw -F
sudo iptables -t raw -X
我现在有：
$ sudo iptables -t nat -L
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
DNAT tcp -- anywhere anywhere tcp dpt:http-alt to:172.22.0.99:8080
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
MASQUERADE all -- anywhere anywhere
现在，如果我连接到 Pi 的无线接入点 172.24.1.1 (wlan0) 并获取 IP 地址 172.24.1.x，我可以通过以下方式访问 Pi 上的 Domoticz Web 服务器：http://172.24.1.1:8080，这就是我想要的。
以前的情况是，我必须通过一个单独的路由器（172.22.0.1），获取IP地址172.22.0.x，并通过eth0访问Pi：http://172.22.0.99:8080。
