How IP pass-through affects 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.

Using pinholes to manage the Digi device

IP pass-through uses a concept called pinholes. The Digi device can be configured 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. Network services and ports that can be configured as pinholes include (see "Network services settings" on page 82 to configure these settings):

Telnet: for accessing the device through a Telnet login and the command-line.

SSH: for accessing to the device through a Secure Shell (SSH) login and the command-line.

HTTP: for accessing the device through HTTP and the web interface.

HTTPS: for accessing to the device through HTTPS and the web interface

SNMP: for monitoring and managing the device through SNMP.
