# Phase 3 - Firewall Rules Implementation
## ✅ Completed: Firewall Rule Management
We've successfully implemented comprehensive firewall rule management as the first part of Phase 3!
### 🎯 What's Working
#### Firewall Rule Features
- **List Rules** - View all configured firewall rules
- **Get Rule Details** - Retrieve specific rule by UUID
- **Create Rules** - Add new firewall rules with full control
- **Update Rules** - Modify existing rules
- **Delete Rules** - Remove rules
- **Toggle Rules** - Enable/disable rules quickly
- **Find Rules** - Search rules by description
- **Rule Presets** - Quick creation of common rules:
- `allow-web` - HTTP/HTTPS traffic
- `allow-ssh` - SSH access
- `allow-minecraft` - Minecraft server (port 25565)
- `block-all` - Block all traffic
### 📝 Example Usage
```javascript
// Create a Minecraft server rule
await create_firewall_preset({
preset: "allow-minecraft",
interface: "lan",
description: "Allow Minecraft server on LAN"
});
// Create a custom rule
await create_firewall_rule({
action: "pass",
interface: "wan",
direction: "in",
protocol: "tcp",
source: "any",
destination: "192.168.1.100",
destinationPort: "3389",
description: "Allow RDP to server"
});
// Find all web-related rules
await find_firewall_rules({
description: "web"
});
// Toggle a rule on/off
await toggle_firewall_rule({
uuid: "rule-uuid-here"
});
```
### 🔧 Technical Details
#### API Endpoints Used
- `/api/firewall/filter/searchRule` - List/search rules
- `/api/firewall/filter/getRule/{uuid}` - Get specific rule
- `/api/firewall/filter/addRule` - Create new rule
- `/api/firewall/filter/setRule/{uuid}` - Update rule
- `/api/firewall/filter/delRule/{uuid}` - Delete rule
- `/api/firewall/filter/apply` - Apply changes
#### Rule Structure
```typescript
interface FirewallRule {
uuid?: string;
enabled: string; // '0' or '1'
action: string; // 'pass', 'block', 'reject'
interface: string; // Interface name
direction: string; // 'in' or 'out'
ipprotocol: string; // 'inet', 'inet6', 'inet46'
protocol: string; // 'any', 'tcp', 'udp', 'icmp'
source_net: string; // Source address/network
source_port?: string; // Source port
destination_net: string; // Destination address/network
destination_port?: string; // Destination port
description?: string; // Rule description
}
```
### 🧪 Testing
Run the firewall rule tests:
```bash
npm run build
npx tsx test-firewall.ts
```
### 📋 Next Steps for Phase 3
- [ ] **NAT/Port Forwarding** - Implement port forward rules
- [ ] **DHCP Management** - Static mappings and configuration
- [ ] **DNS Services** - Host overrides and forwarder settings
- [ ] **Firewall Aliases** - IP, network, and port aliases
### 🚀 Integration with Claude Desktop
The firewall rule tools are fully integrated and ready to use in Claude Desktop. Just ask to:
- "List all firewall rules"
- "Create a rule to allow Minecraft traffic"
- "Block all traffic from a specific IP"
- "Find rules related to web traffic"
- "Disable the SSH rule temporarily"
## 🎉 Success!
We can now manage firewall rules through natural language! This is a major milestone for the OPNsense MCP server.
