firewalld 针对某个端口开放多个IP

# firewalld 针对某个端口开放多个IP

## 添加多个IP访问规则

### 方法一：分别添加每个IP的富规则
```bash
# 为每个IP单独添加规则
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="192.168.1.100" port protocol="tcp" port="2375" accept'
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="192.168.1.101" port protocol="tcp" port="2375" accept'
firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="10.0.0.50" port protocol="tcp" port="2375" accept'
```


### 方法二：使用IP集合（推荐）
```bash
# 创建IP集合
firewall-cmd --permanent --new-ipset=trusted_ips --type=hash:ip
firewall-cmd --permanent --ipset=trusted_ips --add-entry=192.168.1.100
firewall-cmd --permanent --ipset=trusted_ips --add-entry=192.168.1.101
firewall-cmd --permanent --ipset=trusted_ips --add-entry=10.0.0.50

# 基于IP集添加规则
firewall-cmd --permanent --add-rich-rule='rule source ipset="trusted_ips" port protocol="tcp" port="2375" accept'
```


## 验证和管理

### 查看富规则
```bash
firewall-cmd --list-rich-rules
```


### 查看IP集
```bash
firewall-cmd --list-ipsets
firewall-cmd --ipset=trusted_ips --get-entries
```


### 重新加载配置
```bash
firewall-cmd --reload
```


## 删除规则

### 删除单个IP规则
```bash
firewall-cmd --permanent --remove-rich-rule='rule family="ipv4" source address="192.168.1.100" port protocol="tcp" port="2375" accept'
```


### 删除IP集规则
```bash
firewall-cmd --permanent --remove-rich-rule='rule source ipset="trusted_ips" port protocol="tcp" port="2375" accept'
firewall-cmd --permanent --delete-ipset=trusted_ips
```
