4.5 IP Passthrough Setup

You can quickly enable IP passthrough with the IP Passthrough Setup Wizard available under Getting Started → IP
Passthrough Setup. IP passthrough takes a 3G/4G WAN data source (USB, ExpressCard, or CradlePoint business-
grade modem) and passes the IP address through to Ethernet LAN.
Using this function requires many changes to your router configuration. The IP Passthrough Setup Wizard will
automatically make these changes for you: simply read through the wizard and select Enable IP Passthrough on the
second page. For further configuration options, see Network Settings → WiFi / Local Networks.
Review the list of changes to ensure they are compatible with your router needs:
• All Ethernet ports will be set to LAN (i.e. you cannot use Ethernet as an Internet source for your router).
• All WAN devices will have Load Balance disabled and the highest priority device will be used.
• All network groups except the primary network group will be removed.
• All wireless interfaces will be removed from the primary network group. (It is possible to have a wireless interface
associated with another network.)
• All router-based VPN and GRE services will be disabled.
• The Routing Mode will be set to IP Passthrough. (Network Settings → Local Networks in the "Local Network
Editor" under "IP Settings")
• The Subnet Selection Mode will be set to "Automatically Create Subnet". (Network Settings → Local Networks in
the "Local Network Editor" under "IP Settings" – this shows once IP Passthrough is set as the Routing Mode)
Any Ethernet WAN connections should be disconnected before IP passthrough is enabled.
