Feature highlights


LANCOM R&S®Unified Firewalls now support the VPN standard "WireGuard" for simple and fast administration of VPN connections. The use of the noise protocol ensures an efficient handshake that effectively accelerates the establishment of VPN connections. In addition, high data throughput is achieved by reducing encryption parameters.

DNS-based firewall rules

As of LCOS FX 10.12, create firewall rules over and between DNS objects for easier management of dynamic and software-based networks. The use of host names instead of fixed IP addresses makes the creation of firewall rules particularly efficient.


Hardware monitoring

The graphical display of all critical system parameters, such as CPU, RAM, and hard disk utilization, provides a quick and comprehensive overview of the performance and workload of the LANCOM R&S®Unified Firewalls. The assignment of resource consumption to features and processes makes it possible to quickly identify bottlenecks and weak points and to take targeted optimization measures.


Sending security reports by e-mail

Efficient archiving and auditing is made possible by automatically sending security reporting by e-mail at configurable intervals. This offers a clear advantage in terms of monitoring and security of your network, as relevant security information is provided promptly and reliably.
