# Net1 Removed - Issue Analysis

**Date**: 2026-01-21  
**Status**: ⚠️ **ISSUE** - 192.168.11.166 still not accessible after net1 removal

---

## Current Situation

### Configuration
- ✅ **net1 removed**: Container now has only eth0 (192.168.11.166)
- ✅ **Docker network**: Bridge mode with port mappings
- ✅ **docker-proxy**: Listening on 0.0.0.0:80/443/81
- ✅ **Routing**: Clean (only eth0 route)
- ❌ **192.168.11.166**: Not accessible (HTTP 000)
- ⚠️ **Docker container**: Starting (health: starting)

---

## Analysis

### What's Working
1. **Container network**: Clean single interface (eth0)
2. **Docker port mappings**: Correct (0.0.0.0:80/443/81)
3. **docker-proxy**: Running and listening

### What's Not Working
1. **192.168.11.166**: Not accessible from outside
2. **localhost:80**: Not accessible from inside container
3. **Docker container health**: Starting (may need more time)

---

## Possible Causes

### 1. NPMplus Not Fully Started
- Container health shows "starting"
- NPMplus may need more time to initialize
- Nginx inside container may not be running yet

### 2. Docker Container Internal Issue
- NPMplus nginx may not be listening inside container
- Container may be in unhealthy state
- Need to check container logs

### 3. Network Namespace Issue
- Docker bridge network may have routing issues
- Port forwarding may not be working correctly
- Need to verify iptables rules

---

## Diagnostic Steps

### Step 1: Wait for Container to Fully Start
```bash
# Wait 30-60 seconds for NPMplus to fully initialize
# Check health status
docker ps --filter name=npmplus --format "{{.Status}}"
```

### Step 2: Check NPMplus Processes
```bash
docker exec npmplus ps aux | grep nginx
docker exec npmplus ps aux | grep node
```

### Step 3: Check NPMplus Logs
```bash
docker logs npmplus --tail 50
```

### Step 4: Test Direct Connection to Docker Container IP
```bash
# Get container IP
docker inspect npmplus --format "{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}"

# Test connection
curl -I http://<container-ip>:80
```

### Step 5: Check Docker Network
```bash
docker network inspect bridge
docker port npmplus
```

## Recommended Actions

### Immediate
1. **Wait 30-60 seconds** for NPMplus to fully start
2. **Check container health** status
3. **Review container logs** for errors

### If Still Not Working
1. **Check NPMplus nginx** is running inside container
2. **Verify Docker port mappings** are correct
3. **Test direct connection** to Docker container IP (172.17.0.2)
4. **Check iptables rules** for port forwarding

### Alternative Solution
If 192.168.11.166 continues to have issues:
- **Re-add net1** temporarily
- **Use 192.168.11.167** (which was working)
- **Update UDM Pro** to use 192.168.11.167

---

## Next Steps

1. ✅ Wait for container to fully start (30-60 seconds)
2. ✅ Check NPMplus processes and logs
3. ✅ Test direct connection to Docker container IP
4. ✅ If still failing, consider re-adding net1 or investigating Docker networking

---

**Status**: ⏳ **WAITING** - Container may need more time to fully start

**Action**: Wait and re-test, then check container logs if still failing
