All-in-all it is a high-performance basis for no-compromise backup scenarios and highly available networks in any industry.

Secure site connectivity via VPN

The LANCOM 1780VA-4G offers high levels of security. The standard equipment of 5 IPSec VPN channels guarantees strong encryption, secure connections for mobile employees, and protection of corporate data. The LANCOM VPN option upgrades the router to support 25 VPN channels. This ensures that your network is perfectly scalable and can grow on demand - without additional hardware components.

Advanced Routing & Forwarding

The LANCOM 1780VA-4G provides up to 16 securely isolated IP contexts, each of which has its own separate routing. This is an elegant way of operating IP applications with one central router and keeping the different communication channels securely separated from one another.
