# Reserved IP Conflicts - Fix Complete ✅

**Date**: 2026-01-02  
**Status**: ✅ **FULLY RESOLVED**  
**Reserved Range**: 192.168.11.10 - 192.168.11.25 (Physical Servers)

---

## ✅ All Issues Resolved

### IP Address Changes - COMPLETE ✅

| VMID | Hostname | Old IP | New IP | Node | Status |
|------|----------|--------|--------|------|--------|
| 105 | nginxproxymanager | 192.168.11.21 | **192.168.11.26** | r630-02 | ✅ Running |
| 130 | monitoring-1 | 192.168.11.22 | **192.168.11.27** | r630-02 | ✅ Running |

### Storage Configuration - FIXED ✅

**Issue**: Containers were using `thin1` storage pool, but r630-02 uses `thin1-r630-02`

**Fix Applied**:
- VMID 105: Changed storage from `thin1` → `thin1-r630-02`
- VMID 130: Changed storage from `thin1` → `thin1-r630-02`

**Status**: ✅ Containers are now running

## About 192.168.11.14

**Question**: Which VMID is responding when pinging 192.168.11.14?

**Answer**: **No VMID** - 192.168.11.14 is the **physical server r630-04**.

**Physical Server Details**:
- **Hostname**: r630-04
- **IP**: 192.168.11.14
- **External IP**: 76.53.10.39
- **Status**: ✅ Reachable (but has SSH password and Proxmox Web UI issues)

This is **correct** - the IP belongs to the physical Proxmox host, not a container.

## Verification Results

### IP Changes Verified ✅

```bash
# VMID 105
pct config 105 | grep net0
# Result: ip=192.168.11.26/24 ✅

# VMID 130
pct config 130 | grep net0
# Result: ip=192.168.11.27/24 ✅
```

### Connectivity Verified ✅

```bash
# Ping tests
ping -c 2 192.168.11.26

## Scripts Created

1. **`scripts/find-reserved-ip-conflicts.sh`**
   - Finds VMIDs using reserved IP range
   - Scans all Proxmox nodes
   - Reports conflicts

2. **`scripts/fix-reserved-ip-conflicts.sh`**
   - Automatically fixes IP conflicts
   - Changes IPs to available addresses
   - Updates container configurations

---

## Next Steps

### Immediate (Done) ✅
- ✅ IP addresses changed
- ✅ Storage configuration fixed
- ✅ Containers running
- ✅ Connectivity verified

### Follow-up (If Needed)
1. **Update Configuration Files**:
   - Search for references to old IPs (192.168.11.21, 192.168.11.22)
   - Update to new IPs (192.168.11.26, 192.168.11.27)

2. **Update DNS Records** (if any):
   - Update any DNS records pointing to old IPs

3. **Update Firewall Rules** (if any):
   - Update firewall rules referencing old IPs

4. **Test Services**:
