Digi WAN 3G User Manual page 88

If the third-party router's WAN interface is attached to the Digi device's Ethernet port, and the Digi
device's mobile interface receives the IP address 166.213.2.215, the router's WAN port is assigned
the same IP address 166.213.2.215. If the router is receiving the IP address dynamically; the DNS
server addresses, subnet mask, and default gateway information will be filled in automatically. If
the router is configured manually; you need to obtain the DNS information from the mobile service
provider and enter that manually. The subnet mask is 255.255.255.0 and the default gateway is the
same as the mobile IP address with ".1" for the last octet. In other words: if the mobile IP address
is 166.213.2.215, the default gateway is 166.213.2.1.
IP pass-through's effect on network access to Digi devices
When IP pass-through is enabled, the Digi 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.

The Digi 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.
