Configuration through the web interface
93
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.
