Summary

Some Cradlepoint router models have five Ethernet ports that can be configured as either LAN ports, WAN ports, or disabled. By default, they are configured with one WAN port and multiple LAN ports. This article describes how to change the Ethernet port mode on capable Series 3 Cradlepoint routers from LAN to WAN and vice versa.

LAN mode: LAN mode is used for connecting a wired client device (such as computer, printer, switch, or local router) to the Cradlepoint router.

WAN mode: WAN mode is used for connecting a wired WAN source (such as DSL, cable, or satellite modem) to provide an Internet connection to the CradlePoint router and its clients. Disabled mode: The ethernet port is turned off and cannot be used.

Before you continue, please note that any change to the Ethernet switch of the Cradlepoint router will require a reset, during which time all wired clients will be disconnected. Additionally, if you are connected to the Cradlepoint through the port whose function you are trying to change, you may lose access to the router without being able to complete the changes. Please make sure you have an alternate way to connect the router (wirelessly, remotely, through another port, etc.)


Configuration

Configuration Difficulty: Intermediate
  • Step 1: Log into your router's NCOS Page. For help with logging in please click here.
  • Step 2: Click on the Networking tab to expand it.

  • Step 3: Select VLAN Interfaces within the Networking configuration section.

  • Step 4: To change the operational mode of an Ethernet port we will simply move it from one port group to another. In this example, we will turn one of the default LAN ports into a second WAN port and assign it to a new WAN VLAN.

    • Note: In order to use two LAN ports simultaneously the new WAN port must be in it's own VLAN interface.  Otherwise both WAN ports will function but only the port utilized first will be recognized by the Connection Manager until the device is unplugged.

  • Step 5: Place a check next to the LAN port group, then click the Edit button in the menu above.

  • Step 9: Click OK to proceed. The removed port is now available to be added to another port group. In this case, we will attach it to the existing WAN port group.

  • Step 10: Click the Add button above the VLAN interfaces table.

  • Step 11: Perform the following steps in the new VLAN interface editing menu:
    1. Give the VLAN a unique name in the VLAN field
    2. Select the WAN mode from the Mode drop down list
    3. Click on the Add button to assign a new Ethernet port
    4. Select the port we removed from the LAN VLAN interface (in our example it is port 1)
    5. Click the Save button underneath the new port
    6. Click the Save button on the bottom of the VLAN interface editing window

  • Step 12: We have successfully changed the port mode of one of our LAN ports to WAN by moving it to the new VLAN interface. The same process can be used to turn a WAN port into a LAN port, but only one LAN interface is needed unless a second LAN VLAN is desired.
