Description
Fortinet FortiExtender 511F (FEX-511F)
Fortinet FortiExtender 511F is a robust indoor 5G/LTE gateway engineered to deliver ultra-reliable, secure WAN connectivity for enterprises, branch offices, point-of-sale locations, kiosks, healthcare facilities, and remote sites. Designed for seamless integration with Fortinet Secure SD-WAN and the Fortinet Security Fabric, the 511F provides high-performance cellular broadband with intelligent failover, flexible WAN options, and simplified management through FortiOS — giving organisations resilient connectivity with strong security and centralised control.
Key Features & Benefits
5G Sub-6GHz & LTE Broadband Connectivity
-
5G Sub-6GHz support with advanced LTE fallback ensures higher throughput and lower latency than traditional 4G gateways.
-
Dual-SIM architecture for intelligent cellular failover and enhanced uptime — auto-switches based on signal quality, disconnects, or defined policies.
-
Supports CBRS band (LTE/5G N48) for private 5G/LTE deployments, making the 511F ideal for enterprise mobile zones, edge automation, or secure industrial uplinks.
Flexible and Redundant WAN Connectivity
-
5x GE RJ45 WAN/LAN configurable ports including 1 PoE-powered port (IEEE 802.3at, 25.5W) for simplified installation where power outlets are limited.
-
1x SFP port for fiber uplinks enables deployments where fiber connectivity is required or preferred.
-
Traditional wired WAN support is available alongside 5G/LTE, enabling load balancing and multi-path connectivity.
LAN and Local Connectivity
-
Multiple LAN ports allow direct connection of local devices such as switches, FortiGate units in HA pair configurations, or POS hardware.
-
Supports LAN expansion while preserving strong uplinks, ideal for edge deployments that need both local interconnect and WAN resilience.
Security & Management
-
Natively integrates with FortiGate and FortiManager, appearing as a regular interface in FortiOS.
-
Full support for FortiGuard security services and SD-WAN policies, allowing consistent traffic control, segmentation, inspection, and threat protection.
-
WAN load balancing, automatic failover, and session persistence ensure business continuity even during primary ISP outages.
Advanced Edge Capabilities
-
VxLAN extension for Layer-2 domain extension over IPsec back to a central FortiGate, with no extra licensing required.
-
Virtual Routing Redundancy Protocol (VRRP) support for high availability in environments without FortiGate HA pairs — FortiExtender can act as master NAT firewall if the FortiGate becomes unavailable.
-
Out-of-Band Management (OOB) via console and USB provides reliable remote access and troubleshooting paths.
Deployment & Installation
-
Small form factor with PoE support enables convenient placement where 5G/LTE signal is strongest.
-
Supports GPS/GNSS for location-aware use cases.
-
Ideal for:
-
Remote branch broadband
-
Primary or backup WAN for enterprise sites
-
Retail POS and kiosk connectivity
-
Temporary offices and pop-up venues
-
Industrial and IoT edge uplinks
-
CBRS private 5G edge networks
-
