# ML110 Network Configuration Update

## What Was Changed

**Previous Configuration:**
- vmbr0 = nic0 (should be LAN but no IP was obtained)
- vmbr1 = nic1 (had LAN IP 192.168.1.207)

**New Configuration:**
- vmbr0 = nic1 (LAN - should get 192.168.1.207/24)
- vmbr1 = nic0 (WAN - should get public IP from Spectrum modem)

## Status

✅ Configuration file updated: `/etc/network/interfaces`
⚠️ Network reload was initiated
⚠️ Server temporarily unreachable (expected during network change)

## Next Steps

### If Server Becomes Accessible Again

1. **Verify network status:**
```bash
ssh root@192.168.1.207
ip addr show | grep -E "vmbr0|vmbr1" -A 3
ip route show
```

2. **Expected results:**
- vmbr0 should have 192.168.1.207/24 (LAN)
- vmbr1 should have a public IP (WAN)
- Default route should be via vmbr1

### If Server Remains Unreachable

**Access via console/iDRAC to verify:**

1. **Check network interfaces:**
```bash
ip addr show
systemctl status networking
journalctl -u networking -n 50
```

2. **If needed, revert to previous config:**
```bash
# Restore backup
cp /etc/network/interfaces.backup.* /etc/network/interfaces
ifreload -a
```

3. **Or manually check configuration:**
```bash
cat /etc/network/interfaces
# Verify bridges are correct
```

## Current Network Configuration

The configuration file has been updated to:
- vmbr0 (LAN) = nic1 with DHCP, metric 200
- vmbr1 (WAN) = nic0 with DHCP, metric 100

This aligns the bridge assignments with the actual physical connections where nic1 is connected to the LAN.

## Backup Location

Backup of previous configuration saved as:
`/etc/network/interfaces.backup.YYYYMMDD_HHMMSS`
