# Add VLAN 11 Secondary IP Address - Guide
|
|
|
|
**Last Updated:** 2026-01-15
|
|
**Status:** Active Documentation
|
|
**Purpose:** Configure machine to have both current IP and VLAN 11 IP
|
|
|
|
---
|
|
|
|
## Current Configuration
|
|
|
|
- **Primary Interface:** eth0
|
|
- **Current IP:** 192.168.0.4/24
|
|
- **Current Gateway:** 192.168.0.1
|
|
- **Target VLAN 11 IP:** 192.168.11.4/24
|
|
- **VLAN 11 Gateway:** 192.168.11.1
|
|
|
|
---
|
|
|
|
## Option 1: Temporary Configuration (Until Reboot)
|
|
|
|
**Quick Setup:**
|
|
```bash
|
|
sudo ./scripts/unifi/add-vlan11-secondary-ip.sh
|
|
```
|
|
|
|
**Manual Commands:**
|
|
```bash
|
|
# Add secondary IP
|
|
sudo ip addr add 192.168.11.4/24 dev eth0
|
|
|
|
# Add route to VLAN 11 network
|
|
sudo ip route add 192.168.11.0/24 dev eth0 src 192.168.11.4
|
|
|
|
# Verify
|
|
ip addr show eth0 | grep "inet "
|
|
```
|
|
|
|
**Test Connectivity:**
|
|
```bash
|
|
ping -c 3 192.168.11.1 # VLAN 11 gateway
|
|
ping -c 3 192.168.11.10 # ml110
|
|
ping -c 3 192.168.11.11 # r630-01
|
|
ping -c 3 192.168.11.12 # r630-02
|
|
```
|
|
|
|
---
|
|
|
|
## Option 2: Persistent Configuration (Survives Reboot)
|
|
|
|
### Option 2a: Using ifupdown (if /etc/network/interfaces exists)
|
|
|
|
```bash
|
|
sudo ./scripts/unifi/add-vlan11-secondary-ip-ifupdown.sh
|
|
```
|
|
|
|
**Manual ifupdown Configuration:**
|
|
|
|
1. **Edit /etc/network/interfaces:**
|
|
```bash
|
|
sudo nano /etc/network/interfaces
|
|
```
|
|
|
|
2. **Add VLAN 11 alias interface:**
|
|
```
|
|
# VLAN 11 secondary IP address
|
|
auto eth0:11
|
|
iface eth0:11 inet static
|
|
address 192.168.11.4
|
|
netmask 255.255.255.0
|
|
gateway 192.168.11.1
|
|
```
|
|
|
|
3. **Apply configuration:**
|
|
```bash
|
|
sudo ifdown eth0:11 2>/dev/null || true
|
|
sudo ifup eth0:11
|
|
```
|
|
|
|
### Option 2b: Using Netplan (if netplan is installed)
|
|
|
|
```bash
|
|
sudo ./scripts/unifi/add-vlan11-secondary-ip-netplan.sh
|
|
```
|
|
|
|
**Manual Netplan Configuration:**
|
|
|
|
1. **Find netplan config:**
|
|
```bash
|
|
ls /etc/netplan/*.yaml
|
|
```
|
|
|
|
2. **Edit the config file:**
|
|
```bash
|
|
sudo nano /etc/netplan/*.yaml
|
|
```
|
|
|
|
3. **Add VLAN 11 IP to eth0:**
|
|
```yaml
|
|
network:
|
|
version: 2
|
|
renderer: networkd
|
|
ethernets:
|
|
eth0:
|
|
addresses:
|
|
- 192.168.0.4/24 # Current IP
|
|
- 192.168.11.4/24 # VLAN 11 IP (add this)
|
|
gateway4: 192.168.0.1 # Current gateway
|
|
routes:
|
|
- to: 192.168.11.0/24
|
|
via: 192.168.11.1
|
|
nameservers:
|
|
addresses:
|
|
- 192.168.0.1
|
|
- 8.8.8.8
|
|
```
|
|
|
|
4. **Apply configuration:**
|
|
```bash
|
|
sudo netplan try
|
|
sudo netplan apply
|
|
```
|
|
|
|
5. **Verify:**
|
|
```bash
|
|
ip addr show eth0 | grep "inet "
|
|
```
|
|
|
|
---
|
|
|
|
## Verification
|
|
|
|
After configuration, verify:
|
|
|
|
```bash
|
|
# Check IP addresses
|
|
ip addr show eth0 | grep "inet "
|
|
|
|
# Should show:
|
|
# inet 192.168.0.4/24 ... (current IP)
|
|
# inet 192.168.11.4/24 ... (VLAN 11 IP)
|
|
|
|
# Test connectivity
|
|
ping -c 3 192.168.11.1 # VLAN 11 gateway
|
|
ping -c 3 192.168.11.10 # ml110
|
|
ping -c 3 192.168.0.1 # Default gateway (should still work)
|
|
```
|
|
|

|
|
## Benefits
|
|
|
|
With both IPs configured:
|
|
|
|
1. **Access to Default Network:**
|
|
- Can access UDM Pro (192.168.0.1)
|
|
- Can access devices on 192.168.0.0/24
|
|
|
|
2. **Access to VLAN 11:**
|
|
- Can access Proxmox hosts (192.168.11.10-12)
|
|
- Can access services on VLAN 11
|
|
- Can manage VLAN 11 resources
|
|
|
|
3. **Dual Network Access:**
|
|
- Best of both worlds
|
|
- No need to switch networks
|
|
- Can access both simultaneously
|

## Troubleshooting
|
|
|
|
### Issue: Cannot ping VLAN 11 gateway
|
|
|
|
**Possible Causes:**
|
|
1. VLAN 11 gateway not configured on UDM Pro
|
|
2. Network Isolation enabled
|
|
3. Firewall blocking
|
|
|
|
**Solutions:**
|
|
1. Verify UDM Pro VLAN 11 configuration
|
|
2. Check Network Isolation settings
|
|
3. Verify firewall rules
|
|
|
|
### Issue: IP address not persistent after reboot
|
|
|
|
**Solution:** Use netplan configuration (Option 2)
|
|
|
|
### Issue: Route conflicts
|
|
|
|
**Solution:** Check existing routes:
|
|
```bash
|
|
ip route show
|
|
```
|
|
|
|
Remove conflicting routes if needed:
|
|
```bash
|
|
sudo ip route del 192.168.11.0/24
|
|
```
