Devices	This command is supported in Digi Cellular Family products only.
supported
Purpose	Configures the IP pass-through feature. IP pass-through allows a Digi
	Cellular Family device to provide bridging functionality similar to a cable or
	DSL modem, where the Digi Cellular Family device becomes “transparent”
	to the router or connected device. In this case, the router’s WAN interface
	believes it is connected directly to the mobile network, and has no
	knowledge that the Digi Cellular Family device is the mechanism providing
	that connectivity.
	A Digi Cellular Family device configured for IP pass-through, such as a
	ConnectPort WAN or Digi Connect WAN, passes its mobile IP address
	directly through and to the Ethernet device (router or PC) to which it is
	connected through the Ethernet port. From the perspective of the
	connected device, the Digi Cellular Family device essentially becomes
	transparent (similar to the behavior of a cable or DSL modem) to provide a
	bridge from the mobile network directly to the end device attached to the
	Digi Cellular Family device.
	Since the mobile network address is effectively “passed-through” to the
	local device connected to the Ethernet port of the Digi Cellular Family
	device, all network access to it is bypassed, with some specific exceptions.
	Services disabled when IP pass-through is enabled
	When IP pass-through is enabled, the Digi Cellular Family device
	effectively disables all router and IP service functionality. Services that are
	disabled are:
	•	NAT
	•	Port Forwarding
	•	VPN
	•	DDNS updates
	•	Socket Tunnel
	•	Network Services configuration

Services available when IP pass-through is enabled

The Digi Cellular Family device is effectively transparent to all IP activity and network access by other devices, with these exceptions:

•It can be accessed via the serial port for configuration using the command line interface.

•It accepts TCP/IP connections for purposes of configuration by means of a “pinhole” on the mobile interface.

•It can be accessed by other devices on the local Ethernet segment via the default IP address of 192.168.1.1.

•Clients such as SureLink, and client/server services such as Connectware Manager are operational and enabled by default.
