Dual Internet Connections Configuration using Kerio Control Load Balancing #loadbalancing #loadbalancer #kerio #keriocontrol #firewall #dualinternet #network #firewalls Load Balancing Configuration in Kerio Control Firewall Load balancing in Kerio Control helps distribute internet traffic across multiple WAN connections to optimize bandwidth usage, improve redundancy, and ensure failover. Follow the steps below to configure it: ________________________________________ Step 1: Access the Kerio Control Web Interface 1. Open a web browser and enter the Kerio Control management IP (e.g., http://192.168.1.1:4080). 2. Log in using admin credentials. ________________________________________ Step 2: Configure Internet Interfaces 1. Go to Interfaces under Dashboard. 2. Check the status of available WAN connections (e.g., ISP1 and ISP2). 3. If you haven't added multiple WAN connections, click "Add Interface", select Internet, and configure the connection settings (e.g., DHCP, Static, or PPPoE). ________________________________________ Step 3: Enable Load Balancing 1. Navigate to Traffic Rules → Select Internet Interfaces. 2. Click on the Load Balancing tab. 3. Enable Load Balancing by checking "Enable Load Balancing". 4. Adjust the Weight Percentage (%) for each WAN connection. o Example:  ISP1 (Primary) → 70%  ISP2 (Secondary) → 30% 5. Click Apply. ________________________________________ Step 4: Configure Failover (Optional but Recommended) 1. In the Load Balancing section, enable Failover by checking "Use Interface for Failover". 2. Set a Health Check Method (Ping, TCP, or HTTP). 3. Define a Failover Threshold (e.g., if a WAN connection fails for 10 seconds, switch to the backup). 4. Click Apply and Save Changes. ________________________________________ Step 5: Define Traffic Rules (Optional - Policy-Based Load Balancing) To route specific traffic through a preferred WAN: 1. Go to Traffic Rules → Click Add Rule. 2. Set the Source (e.g., LAN subnet or specific IP). 3. Set the Destination (e.g., Any or specific website). 4. Under Action, select "Route through specific Internet Interface" and choose the WAN interface. 5. Click OK → Apply the changes. ________________________________________ Step 6: Test and Monitor Load Balancing 1. Go to the Status tab and check the Interfaces section. 2. Test failover by disconnecting a WAN link and ensuring traffic switches automatically. 3. Use ping, traceroute, or speed tests to confirm traffic distribution. ________________________________________ Conclusion By configuring Load Balancing in Kerio Control, you ensure optimal internet utilization, improve network performance, and enable automatic failover in case of link failure.
