When an XPON ONU SFP stick is plugged directly into a router, internet access can work while the ONU's management page remains unreachable.

I use an XPON ONU SFP stick in a TP-Link ER8411, managed through Omada SDN. Internet worked over PPPoE using the VLAN required by my ISP, but I couldn't access the ONU management interface.

You can reach ONU management interface by adding a static Virtual WAN on the same SFP port. This gives the router an address on the ONU's local network while PPPoE continues using the VLAN required by your ISP.

## Configuration

You'll need router firmware and an Omada controller version that support Virtual WAN. Keep the physical WAN configured for PPPoE with VLAN 100.

Open Site View → Network Config → Internet → Virtual WAN → Create New Virtual WAN. Depending on your controller version, Internet settings may appear under Settings → Wired Networks.

Configure the new connection:

| Setting               | Value                                                |
| --------------------- | ---------------------------------------------------- |
| Name                  | ONUManagement                                        |
| Physical WAN          | SFP port containing the ONU                          |
| Connection type       | Static IP                                            |
| IP address            | An unused IP address in the ONU's management subnet  |
| Subnet mask           | The subnet mask used by the ONU's management network |
| Default gateway       | The ONU's management IP address                      |
| MTU                   | 1480                                                 |
| VLAN                  | Disabled                                             |
| Load balancing weight | 0                                                    |

The Virtual WAN IP belongs to the ER8411 and must be different from the ONU's management IP. Keep the load balancing weight at 0 so ordinary internet traffic continues through PPPoE.

After saving, open the ONU interface using: `http://<ONU-management-IP>`

⚠️

The ONU's management subnet (ONU LAN) must not overlap with any LAN VLAN subnet in your network. Overlapping subnets can cause routing problems.

TP-Link documents this connection setup in its [Virtual WAN configuration guide](https://support.omadanetworks.com/us/document/40179/?ref=developerinsider.co).
