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 you
configured the router 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.
Effect of IP pass-through on network access to Digi device
When IP pass-through is enabled, the Digi device effectively disables all router and IP service
functionality. Services that are disabled are:
n
NAT
n
Port forwarding
n
VPN
n
DDNS updates
n
Socket tunnel
n
Network Services configuration
The Digi device is effectively transparent to all IP activity and network access by other devices, with
these exceptions:
n
You can access it via the serial port for configuration using the command line interface.
n
It accepts TCP/IP connections for purposes of configuration by means of a “pinhole” on the
mobile interface.
n
Other devices can access it on the local Ethernet segment via the default IP address of
192.168.1.1.
Using pinholes to manage the Digi device
IP pass-through uses a concept called
pinholes
. You can configure a Digi device to listen on specific TCP
ports, and terminate those connections at the Digi device for purposes of managing it. Those ports are
called pinholes, and they are not passed on to the device connected to the Ethernet port of the Digi
device. You can configure network services and ports as pinholes include (see
to configure these settings):
n
HTTP
: for accessing the device through HTTP and the web interface.
n
HTTPS
: for accessing to the device through HTTPS and the web interface.
n
Telnet
: for accessing the device through a telnet login and the command-line.
n
SSH
: for accessing the device through a Secure Shell (SSH) login and the command-line.
n
SNMP
: for monitoring and managing the device through SNMP.
n
Ping
: for accessing the device through ICMP echo (ping) requests.
Remote Manager and Digi SureLink ports are automatically set up as pinholes so that they continue to
work with the Digi device. In addition, the Digi device uses a private address on the Ethernet interface
strictly for use in configuration or local access. This allows a user on the local network to gain access
to the web interface or a telnet session in order to make configuration changes.
