Configuration through the web interface

Using pinholes to manage the Digi device

IP pass-through uses a concept called pinholes. A 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 64 to configure these settings):

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

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

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

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

line.

 SNMP: for monitoring and managing the device through SNMP.

 Ping: for accessing the device through ICMP echo (ping) requests.

Device 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.

Remote device management and IP pass-through

As illustrated above, the Digi device allows you to enable pinholes for specific ports to allow

remote users to manage the Digi device from the mobile network or open Internet. The Digi device

retains its remote management capabilities using Device Manager. The necessary pinholes are

automatically defined when the Digi device is configured for IP Pass-through.This provides

administrators with the same remote-management capabilities that exist in Digi remote devices.

Steps to configure IP pass-through

To configure IP Pass-through from the web interface for your Digi device, follow these steps, or, in

the case of the first three steps, make sure they have been performed.

1 Set a static IP address for the Digi device. Go to Configuration > Network > IP Settings.

2 Set up the DHCP server. Go to Configuration > Network > DHCP Server Settings. See

page 60 and the online help for DHCP Server Settings.

3 Turn on the DHCP server. Go to Management > Network Services. In

DHCP Server Management, click the Start button.

4 Configure IP pass-through settings. Go to Configuration > Network > IP Pass-through.

IP pass-through settings include:

– Enable IP Pass-through: Enables or disables IP Pass-through.

– Pinhole Configuration: Specifies whether specific network services/ports are

configured as pinholes for purposes of managing the Digi device.

5 Click Apply.
