# Proxmox Firewall Check Report

**Date**: 2026-01-21  
**Status**: ✅ **Proxmox Firewall Not Blocking Traffic**

---

## Summary

**Proxmox firewall is disabled on both hosts**, so it is **NOT blocking external traffic** to NPMplus or VMID 5000.

---

## Host Firewall Status

### r630-01 (NPMplus Host)
- **Firewall Status**: `disabled/running`
- **Impact**: Firewall is disabled, not blocking any traffic
- **VMID 10233 (NPMplus)**: No firewall restrictions

### r630-02 (VMID 5000 Host)
- **Firewall Status**: `disabled/running`
- **Impact**: Firewall is disabled, not blocking any traffic
- **VMID 5000 (Blockscout)**: No firewall restrictions

---

## Firewall Configuration Files

### Host Firewall Configs
- **r630-01**: No host firewall config file found (or empty)
- **r630-02**: No host firewall config file found (or empty)

### Cluster Firewall Config
- **Status**: No cluster firewall config found (or empty)

### Container Firewall Configs
- **VMID 10233 (NPMplus)**: No firewall option in container config
- **VMID 5000 (Blockscout)**: No firewall option in container config

## Conclusion

✅ **Proxmox firewall is NOT the issue**

The Proxmox firewall is disabled on both hosts, so it cannot be blocking external traffic. The timeout issue is **NOT caused by Proxmox firewall**.

---

## Root Cause Analysis

Since Proxmox firewall is not blocking:

1. **UDM Pro Firewall** - Most likely cause:
   - Rule order issue (block rules before allow rules)
   - Zone-based firewall blocking External → Internal
   - Port forwarding rules not enabled

2. **ISP Blocking** - Possible cause:
   - Some ISPs block ports 80/443
   - Test from different network/location

3. **Network Routing** - Less likely:
   - Traffic not reaching UDM Pro
   - WAN interface not receiving traffic

---

## Next Steps

Since Proxmox firewall is not the issue, focus on:

1. **UDM Pro Firewall Rule Order**:
   - Verify "Allow Port Forward..." rules are at the top
   - Ensure no "Block External → Internal" rules are above them

2. **Test from Different Location**:
   - Test from mobile hotspot
   - Test from VPN
   - This will determine if ISP is blocking

3. **Check UDM Pro Logs**:
   - Look for blocked connections
   - Identify which rule is blocking (if any)

## Verification

**Proxmox hosts are NOT blocking traffic:**
- ✅ Firewall disabled on r630-01
- ✅ Firewall disabled on r630-02
- ✅ No firewall rules configured
- ✅ Containers have no firewall restrictions

**The issue is elsewhere:**
- ⚠️ UDM Pro firewall (most likely)
- ⚠️ ISP blocking (possible)
- ⚠️ Network routing (less likely)

**Status**: ✅ **Proxmox Firewall Check Complete - Not Blocking**
