Optimizing performance with LSO

Kerio Control includes large segment offload, also referred to as generic segmentation offload. LSO allows the network interface controller to process the segmentation of a data transfer and significantly improves performance. However, these improvements are noticeable only during large data transfers, such as file downloads, or video streams.

The throughput gain depends on the particular deployment. For example, you can expect up to 400 Mbps on the Kerio Control NG100 hardware appliance.

Blocking incoming connections from specified countries

Kerio Control allows you to filter incoming traffic by country (GeoIP). Kerio Control then blocks all IP addresses that belong to the countries specified in the filter.

IPsec VPN tunnel configuration update

Kerio Control 9.2 adds a detailed configuration for IKE and ESP ciphers used in IPsec VPN tunnels. With this detailed configuration you can easily create IPsec VPN tunnels with third-party firewalls.
