Router LANCOM 1926VAG-4G nero 1U metallo antenna esterna

The LANCOM 1926VAG-4G is a high-end SD-WAN gateway designed for high availability in branch and enterprise networks. It combines two VDSL Supervectoring modems in a single device to provide up to 2x 300 Mbps when both connections are active, and can alternatively operate one modem on a G.fast gigabit link. An integrated dual‑SIM LTE Advanced modem provides mobile backup. The device supports LANCOM SD-WAN features for automated, secure VPN connectivity and is suited for mission-critical, performance-demanding SD-WAN scenarios.

Advantages

The LANCOM 1926VAG-4G supports multi‑WAN and backup scenarios with two integrated VDSL Supervectoring modems or one G.fast modem, an SFP port for fiber, WAN Ethernet for external modems, and a dual‑SIM LTE Advanced modem up to 300 Mbps. Load balancing enables active/active operation of multiple Internet connections to maximize available bandwidth and availability. LANCOM SD‑WAN with Auto‑VPN, High Scalability VPN (HSVPN) and Advanced Mesh VPN enables centralized, automated VPN setup and efficient scaling for many branches. The device offers professional telephony functions via the integrated Voice Call Manager (VCM) and session border controller (SBC), and it comes in a full‑metal housing with front‑facing ports for easy 19" rack installation.

How to use

Install the LANCOM 1926VAG-4G in a 19" rack or on a flat surface and connect the required WAN interfaces: insert DSL lines into the VDSL ports or connect fiber via SFP, attach an external WAN Ethernet modem if needed, and insert up to two SIM cards for LTE backup. Configure SD‑WAN and Auto‑VPN centrally via the LANCOM Management Cloud or locally using the device management interface. Define multiple WAN connections for active/active load balancing, set dynamic path selection and traffic steering policies for application‑aware routing, and enable HSVPN when consolidating multiple networks into a single scalable VPN tunnel. For telephony, provision SIP/ISDN/analog endpoints through the integrated VCM and configure QoS to prioritize voice traffic.

Recommendations

Use the dual‑VDSL or G.fast plus LTE combination to ensure uninterrupted connectivity in mission‑critical sites. Enable load balancing and Dynamic Path Selection to maximize throughput and resilience, and consider the LANCOM VPN 100 Option if you need up to 100 simultaneous VPN connections as your number of remote sites grows.
