+## 防火墙
+
+防火墙是独立客户区页面，支持：
+
+- 查看防火墙启用状态、默认动作和规则列表
+- 启用 / 停用防火墙
+- 设置默认动作：未匹配拒绝或未匹配放行
+- 添加规则
+- 编辑规则
+- 删除规则
+- 单独启用 / 停用某条规则
+
+页面会先在前端修改规则列表和开关状态，点击“保存设置”后才统一同步到 CLICD。这样可以避免每次切换开关、修改默认动作或编辑规则时都立即请求后端，减少客户区卡顿。
+
+注意：防火墙关闭时也可以保存规则；关闭只表示暂时不接管该容器流量，不代表规则必须清空。
+
+使用的 CLICD API：
+
+```text
+GET /api/v1/containers/{id}/firewall
+PUT /api/v1/containers/{id}/firewall
+```
+
+更新防火墙时必须使用 JSON 请求体，例如：
+
+```json
+{
+  "enabled": true,
+  "default_action": "ACCEPT",
+  "rules": [
+    {
+      "id": "",
+      "network": "ipv4",

+      "protocol": "tcp",

+      "action": "ACCEPT",
+      "description": "Allow SSH",
+      "enabled": true
+    }
+  ]
+}
+```
+
+规则字段说明：
+
+| 字段 | 说明 |
+| --- | --- |
+| `network` | 网络范围，常用 `ipv4`，也支持 `ipv6` / `all` |
+| `direction` | 方向，`in` 入站，`out` 出站 |
+| `protocol` | 协议，`tcp` 或 `udp` |
+| `port` | 端口，可填写单端口、逗号分隔端口或端口段，例如 `22`、`80,443`、`8000-9000` |
+| `source_ip` | 来源 IP / CIDR，留空表示任意来源 |
+| `action` | 动作，`ACCEPT` 放行，`DROP` 拒绝 |
+| `description` | 规则描述 |
+| `enabled` | 是否启用该规则 |
+
+IPv4 NAT 入站规则的端口按容器内部端口匹配，不是宿主机公网端口。例如公网 `22023 -> 容器 22`，防火墙规则端口应填写 `22`。

+### 防火墙获取提示“不支持的方法”
+
+请确认模块版本已经包含防火墙页签修复。客户区防火墙列表应通过模块公开的 `firewallList` 调用，再由模块向 CLICD 发起：
+
+```text
+GET /api/v1/containers/{id}/firewall
+```
+
+如果页面或二开代码直接把读取请求改成 `POST /api/v1/containers/{id}/firewall`，CLICD 会返回“不支持的方法”。
+
+### 防火墙保存后规则为空
+
+请确认更新接口最终发往 CLICD 的请求体是 JSON，并且包含 `rules` 数组。防火墙关闭时也可以保存规则，`enabled: false` 不应自动清空 `rules`。
+
+正确请求体示例：
+
+```json
+{
+  "enabled": false,
+  "default_action": "ACCEPT",
+  "rules": [
+    {
+      "id": "",
+      "network": "ipv4",

+| Field | Description |
+| --- | --- |
+| `name` | API key name. Required when creating a key. |
+| `ip_whitelist` | Optional allowed source IPs/CIDRs, comma-separated. Empty means no IP restriction. |
+| `scopes` | Optional permission scopes. If omitted, the default read-only scopes are used. `*` grants all permissions. |
+| `expires_at` | Optional expiration time. Empty means no expiration. |
+| `disabled` | Whether this key is disabled. |
+| `container_uuids` | Optional container allowlist that limits the key to specific containers. |
