+# 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`
+
