Deploy Now - Option 1: All NICs with DHCP

Current Status

✅ Script network-config-dhcp-all.sh is ready ✅ Configuration will set up DHCP on ALL physical NICs ✅ Script will detect which NICs get IP addresses

Deployment Steps

Step 1: Ensure Script is on R630 (pve2)

If you're already on R630, check if the script exists:

cd /opt/proxmox-network-config
ls -la network-config-dhcp-all.sh

If it doesn't exist, transfer it from your project:

# From your development machine (if accessible):
scp -i ~/.ssh/id_ed25519_proxmox infrastructure/proxmox/network-config-dhcp-all.sh root@192.168.1.49:/opt/proxmox-network-config/

# OR manually copy the script content to the server

Step 2: Make Script Executable

cd /opt/proxmox-network-config
chmod +x network-config-dhcp-all.sh

Step 3: Preview Configuration (Recommended)

cd /opt/proxmox-network-config
DRY_RUN=true ./network-config-dhcp-all.sh

Review the output to see:

• Which NICs will be configured
• What bridges will be created
• The complete /etc/network/interfaces configuration

Step 4: Deploy Configuration

cd /opt/proxmox-network-config
./network-config-dhcp-all.sh

The script will:

1. ✅ Backup existing /etc/network/interfaces
2. ✅ Detect all physical NICs
3. ✅ Create DHCP bridges for each NIC
4. ✅ Apply the configuration
5. ✅ Wait for DHCP to assign IPs
6. ✅ Show which bridges got IP addresses

Step 5: Verify Deployment

After deployment completes:

# Check all bridges
ip addr show | grep -A 5 "vmbr"

# Check which bridges have IPs
for br in vmbr0 vmbr1 vmbr2 vmbr3 vmbr4; do
    echo -n "$br: "
    ip addr show $br 2>/dev/null | grep "inet " | awk '{print $2}' || echo "No IP"
done

# Check routing
ip route show

# Test connectivity
ping -c 3 192.168.1.1  # LAN gateway (if vmbr0 has LAN IP)
ping -c 3 8.8.8.8      # Internet (if WAN interface got IP)

What to Expect

If R630 has 4 NICs (nic0, nic1, nic2, nic3):

Configuration:

• nic0 → vmbr0 (DHCP)
• nic1 → vmbr1 (DHCP)
• nic2 → vmbr2 (DHCP)
• nic3 → vmbr3 (DHCP)

After DHCP:

• vmbr0 (nic0): Will get IP if connected to LAN
• vmbr1 (nic1): Will get IP if connected
• vmbr2 (nic2): Will get IP if connected to Spectrum modem
• vmbr3 (nic3): Will get IP if connected

Example Output

✓ vmbr0 (nic0): 192.168.1.49/24      ← LAN (192.168.1.0/24)
✗ vmbr1 (nic1): No IP address        ← Not connected
✓ vmbr2 (nic2): 203.0.113.10/24      ← WAN (Public IP from Spectrum)
✗ vmbr3 (nic3): No IP address        ← Not connected

Troubleshooting

No IPs Assigned

If no interfaces get IPs:

• Wait 10-15 seconds (DHCP can take time)
• Check cables are connected
• Verify DHCP servers are available
• Manually request DHCP: dhclient -v vmbr0

Wrong Interfaces Selected

The script configures ALL physical NICs, so you'll see which ones get IPs. No manual selection needed - DHCP determines connectivity.

Restore Backup

If something goes wrong:

# List backups
ls -la /etc/network/interfaces.backup.*

# Restore most recent
cp /etc/network/interfaces.backup.* /etc/network/interfaces
systemctl restart networking

Next Steps After Deployment

1. ✅ Identify which bridge got LAN IP (192.168.1.x)
2. ✅ Identify which bridge got WAN IP (public IP)
3. ✅ Verify Proxmox web interface accessible
4. ✅ Configure VMs to use appropriate bridges
5. ✅ Deploy same configuration on ML110

Quick Command Reference

# Deploy
cd /opt/proxmox-network-config && ./network-config-dhcp-all.sh

# Check status
ip addr show | grep vmbr

# Check IPs
for br in vmbr{0..4}; do ip addr show $br 2>/dev/null | grep inet; done

# Restart networking if needed
systemctl restart networking
