Core Capabilities
Cellular access without the rack-scale footprint.
Duckfone is focused on the capabilities distributed sites need most: connectivity, console recovery, secure access, flexible deployment, and automation.
Cellular Continuity
Global 4G LTE with dual SIM provides a separate cellular path for primary or secondary WAN connectivity and out-of-band access.
Direct Console Recovery
Four serial ports give administrators direct access to routers, switches, firewalls, and other serial-managed infrastructure.
PoE+ Deployment
Power over Ethernet supports simple installation in locations where adding a dedicated power outlet is inconvenient.
Secure Remote Access
WireGuard VPN, TACACS+, RADIUS, Active Directory/OpenLDAP, local fallback, and OpenID-based SSO support secure administration.
Automation & Provisioning
Zero Touch Provisioning and REST API capabilities help teams standardize deployment and management workflows.
Centralized Management
Gearlinx ZERO provides the centralized management layer for Duckfone, bringing device access, visibility, lifecycle management, warranty, and support into one operational experience.
How Duckfone Works
A separate cellular path to the infrastructure that matters.
Duckfone can use Ethernet or cellular connectivity and can provide remote access to connected serial infrastructure when the primary network is unavailable.
Duckfone is managed through Gearlinx ZERO for centralized access and operational visibility, while supported local methods such as WebUI, SSH, and CLI remain available for device-level administration.
ZERO is the standard management platform for Duckfone, providing centralized access, fleet visibility, lifecycle management, warranty, and support across deployments.

Flexible Operating Modes
One appliance. Multiple ways to keep a site connected.
Duckfone can be deployed as a cellular gateway, a four-port serial out-of-band appliance, or as part of a wired/cellular failover strategy.
Cellular Gateway + Console Safety Net
Use cellular connectivity for the network device while connecting serial console ports to the same device and other critical infrastructure for recovery access.
Standalone 4-Port OOB
Use Duckfone as a compact out-of-band management appliance with Ethernet and serial services for branch and remote infrastructure.
Wired + Cellular Resilience
Use Ethernet as the normal WAN path with cellular as a secondary path, or use cellular as the primary path, depending on the site design.
Where Duckfone Fits
Built for infrastructure outside the data center.
Duckfone is strongest where space is limited, on-site IT support is scarce, and a network interruption can quickly turn into an expensive truck roll.
