LANCOM 1800VAW-4G SD-WAN modem VDSL2/ADSL2+ (Annex A/B/J)

The LANCOM SD-WAN gateway LANCOM 1800VAW-4G provides a high-availability, multi-interface router for company sites and branch offices that require reliable Internet connectivity for business-critical applications. It combines VDSL Supervectoring and fiber-ready interface diversity with an integrated 4G modem for automatic backup in case of wired-line failure, and adds dual-band concurrent Wi‑Fi 6 for wireless client connectivity. Centralized, automated network management via the LANCOM Management Cloud (LMC) and SD‑WAN features simplify deployment and ongoing operation.

Advantages

The device supports VDSL Supervectoring, VDSL2 and ADSL2+ on copper lines with up to 300 Mbps and includes a Cat‑6 4G modem (LTE‑Advanced up to 300 Mbps) for resilient WAN backup. SD‑WAN functionality with Auto‑VPN, High Scalability VPN (HSVPN) and Advanced Mesh VPN enables centralized, automated and scalable inter-site networking. Dual‑band concurrent Wi‑Fi 6 delivers simultaneous throughput for 2.4 GHz and 5 GHz clients, while a stateful inspection firewall, VLAN and ARF-based segmentation provide layered security. The unit offers flexible mounting options and is produced with attention to sustainability and long-term software support from a German manufacturer.

Suitable for (tasks / use cases)

• Branch office router with automatic Internet backup via 4G
• Centralized SD‑WAN deployments and multi‑site VPN networks
• Small to medium office WLAN with Wi‑Fi 6 client support
• Secure segmentation of guest, employee and IoT networks
• Companies requiring future‑proof hardware with long‑term updates

Key specifications

• Interfaces: VDSL Supervectoring, VDSL2, ADSL2+, fiber-ready options, integrated 4G (Cat. 6)

• WAN features: SD‑WAN with Auto‑VPN, Dynamic Path Selection, Dynamic Traffic Steering, load balancing (active/active)
• Security: Stateful inspection firewall, intrusion prevention, DoS protection, ARF and VLAN segmentation
• VPN: 5 integrated IPSec channels (expandable to 25 with LANCOM VPN Option)
• Ethernet LAN ports: 5 x RJ‑45
• Product colour: Black; Weight: 0.8 kg

How to use

Install the SD‑WAN gateway at the site and connect the primary WAN (VDSL/fiber) and, if required, insert an active SIM for 4G backup. Use the LANCOM Management Cloud to perform an automated initial configuration, provision Auto‑VPN tunnels between sites, and apply security and VLAN policies centrally. Connect wired devices to the RJ‑45 LAN ports and allow wireless clients to join via Wi‑Fi 6. Monitor link status and performance through the management platform and configure Dynamic Path Selection and load balancing to distribute traffic across available WAN links.

Recommendations

For high availability, define at least two WAN connections (primary and backup) and enable active/active operation where possible. Keep the device firmware up to date via the LANCOM Management Cloud and plan VPN channel requirements in advance if you expect to scale beyond the five integrated IPSec tunnels.
