                       └─ r630-02.d-bis.org
```

## Configuration from .env

```bash
PROXMOX_HOST=192.168.11.10          # ml110-01
PROXMOX_PORT=8006
PROXMOX_USER=root@pam
PROXMOX_TOKEN_NAME=mcp-server
PROXMOX_TOKEN_VALUE=***             # Configured ✅

OMADA_CONTROLLER_URL=https://192.168.11.8:8043
```

## Tunnel Configurations

### Tunnel Infrastructure
- **Container**: VMID 102
- **Host**: 192.168.11.12 (r630-02)
- **Network**: 192.168.11.0/24 (can access all Proxmox hosts)

### Active Tunnels

| # | Tunnel Name | Tunnel ID | Public URL | Internal Target | Metrics Port |
|---|-------------|-----------|------------|-----------------|--------------|
| 1 | tunnel-ml110 | ccd7150a-9881-4b8c-a105-9b4ead6e69a2 | ml110-01.d-bis.org | 192.168.11.10:8006 | 9091 |
| 2 | tunnel-r630-01 | 4481af8f-b24c-4cd3-bdd5-f562f4c97df4 | r630-01.d-bis.org | 192.168.11.11:8006 | 9092 |
| 3 | tunnel-r630-02 | 0876f12b-64d7-4927-9ab3-94cb6cf48af9 | r630-02.d-bis.org | 192.168.11.12:8006 | 9093 |

## Conflicts Identified

### ✅ No Port Conflicts
- Each tunnel uses different metrics ports (9091, 9092, 9093)
- All tunnels correctly target port 8006 on different hosts
- No overlapping port usage

### ⚠️ Network Segmentation Conflict
- **Issue**: Your machine (192.168.1.0/24) cannot reach Proxmox network (192.168.11.0/24)
- **Impact**: Direct API access blocked
- **Status**: Expected behavior - different network segments

### ✅ Tunnel Configuration Correct
- All tunnels properly configured
- DNS records point to tunnels
- Services running on VMID 102
- No configuration conflicts

## Solutions

### Solution 1: SSH Tunnel (Best for API Access)

```bash
# Terminal 1: Start tunnel
./setup_ssh_tunnel.sh

# Terminal 2: Use API
PROXMOX_HOST=localhost python3 list_vms.py

# When done: Stop tunnel
./stop_ssh_tunnel.sh
```

**Pros**: 
- Works for API access
- Secure
- Uses existing SSH access

**Cons**: 
- Requires SSH access to Proxmox host
- Two terminals needed

### Solution 2: Cloudflare Tunnel (Best for Web UI)

Access Proxmox web interface via:
- https://ml110-01.d-bis.org
- https://r630-01.d-bis.org  
- https://r630-02.d-bis.org

**Pros**:
- Works from anywhere
- No SSH needed
- Secure (Cloudflare Access)

**Cons**:
- Web UI only (not API)
- Requires Cloudflare Access login

### Solution 3: Run from Proxmox Network

Copy scripts to machine on 192.168.11.0/24 and run there.

**Pros**:
- Direct access
- No tunnels needed

**Cons**:
- Requires machine on that network
- May need VPN

### Solution 4: Shell Script via SSH

```bash
export PROXMOX_HOST=192.168.11.10
export PROXMOX_USER=root
./list_vms.sh
```

**Pros**:
- Uses pvesh via SSH
- No API port needed

**Cons**:
- Requires SSH access
- Less feature-rich than Python script

## Tunnel Management

### Check Status
```bash
ssh root@192.168.11.12 "pct exec 102 -- systemctl status cloudflared-*"
```

### Restart Tunnels
```bash
ssh root@192.168.11.12 "pct exec 102 -- systemctl restart cloudflared-*"
```

### View Logs
```bash
ssh root@192.168.11.12 "pct exec 102 -- journalctl -u cloudflared-* -f"
```

### Test Tunnel URLs
```bash
curl -I https://ml110-01.d-bis.org
curl -I https://r630-01.d-bis.org
curl -I https://r630-02.d-bis.org
```

- `TUNNEL_ANALYSIS.md` - Detailed tunnel analysis
- `TUNNEL_SOLUTIONS.md` - Quick reference solutions
- `COMPLETE_TUNNEL_ANALYSIS.md` - This file
- `TROUBLESHOOT_CONNECTION.md` - Connection troubleshooting

### Scripts
- `list_vms.py` - Main Python script (original)
- `list_vms.sh` - Shell script alternative

- `stop_ssh_tunnel.sh` - Stop SSH tunnel
- `test_connection.sh` - Connection testing

## Recommendations

1. **For API Access**: Use SSH tunnel (`setup_ssh_tunnel.sh`)
2. **For Web UI**: Use Cloudflare tunnel URLs
3. **For Automation**: Run scripts from Proxmox network or use SSH tunnel
4. **For Monitoring**: Use tunnel health check scripts

## Next Steps

1. Test SSH tunnel: `./setup_ssh_tunnel.sh`
2. Verify tunnel URLs work in browser
3. Use appropriate solution based on your needs
4. Monitor tunnel health regularly

## Summary

✅ **Tunnels**: All configured correctly, no conflicts  
✅ **Configuration**: .env file properly set up  
⚠️  **Network**: Segmentation prevents direct access (expected)  
✅ **Solutions**: Multiple working options available  
✅ **Scripts**: All tools ready to use
