## Diagnosis Commands Run

### 1. System Information
```bash
uname -a
```

### 2. Port Forwarding Rules (NAT Table)
```bash
iptables -t nat -L PREROUTING -n -v | grep "76.53.10.36"
```

**What to check:**
- Should show DNAT rules for 76.53.10.36:80 → 192.168.11.166:80
- Should show DNAT rules for 76.53.10.36:443 → 192.168.11.166:443

### 3. Firewall Rules (FORWARD Chain)
```bash
iptables -L FORWARD -n -v | head -40
```

**What to check:**
- Look for ACCEPT rules for 192.168.11.166:80
- Look for ACCEPT rules for 192.168.11.166:443
- Check rule order (allow before block)

### 4. Firewall Rules for NPMplus
```bash
iptables -L FORWARD -n -v | grep -i "192.168.11.166"
```

**What to check:**
- Should show ACCEPT rules
- Should NOT show DROP/REJECT rules

## Expected Findings

### If Port Forwarding is Working:
```
DNAT       tcp  --  0.0.0.0/0      76.53.10.36        tcp dpt:80  to:192.168.11.166:80
DNAT       tcp  --  0.0.0.0/0      76.53.10.36        tcp dpt:443 to:192.168.11.166:443
```

### If Firewall Allows Traffic:
```
ACCEPT     tcp  --  0.0.0.0/0      192.168.11.166     tcp dpt:80
ACCEPT     tcp  --  0.0.0.0/0      192.168.11.166     tcp dpt:443
```

## Next Steps

Based on the diagnosis results:

1. **If NAT rules are missing**: Enable port forwarding rules in Web UI
2. **If firewall is blocking**: Add allow rules or reorder rules in Web UI
3. **If rules are disabled**: Enable them in Web UI
4. **If rule order is wrong**: Reorder rules in Web UI
