Change WAN port to act as LAN port
On Proroute routers, the dedicated Ethernet WAN port can be reconfigured to function as an additional LAN port. This is useful when the router's primary WAN connection is cellular and the Ethernet WAN port is not in use.
Note: When the WAN port is converted to a LAN port, Ethernet WAN failover is disabled. The router will use the cellular connection as its sole WAN interface.
When to use this
| Scenario | Detail |
|---|---|
| Primary WAN is cellular | The SIM-based mobile connection is the internet source. The Ethernet WAN port is unused and can be repurposed. |
| Additional LAN ports required | More wired devices than available LAN ports — gaining an extra port avoids the need for an external switch. |
| Simplified wiring | All Ethernet connections from the router go to the same LAN segment. |
Configuration
Location in WebUI: Network > Operation Mode
- Log in to the WebUI at
http://192.168.8.1(or your configured LAN IP) - Navigate to Network > Operation Mode
- Tick the checkbox "Wired WAN acts as LAN"
- Click Save and Apply
| Network > Operation Mode | |
| Wired WAN acts as LAN | ✓ |
| Save and Apply | |
The change takes effect immediately after saving. The former WAN port becomes part of the LAN bridge and behaves identically to the other LAN ports.
Reverting the change
- Navigate to Network > Operation Mode
- Untick "Wired WAN acts as LAN"
- Click Save and Apply
The port will resume its WAN role and Ethernet WAN failover functionality will be restored.
Considerations
| Consideration | Detail |
|---|---|
| Failover | Ethernet WAN failover is disabled while the WAN port is in LAN mode. If Ethernet failover is required, revert the setting. |
| Port speed | The converted port retains its original speed capability — typically 10/100 Mbps or Gigabit depending on the router model. |
| VLAN support | The port joins the default LAN bridge. Additional configuration is required if VLAN segmentation is needed on this port. |
| PoE passthrough | If the router model supports PoE, confirm whether the WAN port supports PoE passthrough when operating in LAN mode. |
