Configuring a routing table in Kerio Control

Author: Suman Sesham Updated

Overview

Kerio Control allows you to view and edit the IPv4 and IPv6 routing tables. Kerio Control works with the operating system's routing table as well as with the static routes created in Kerio Control.

 

Solution

To modify the routing table, in the administration interface, go to the Routing Table section. Note separate tabs for IPv4 and IPv6.

NOTE

If multiple Internet links are in network load balancing mode, Kerio Control displays only a single default route which is routed through the link with the highest link weight.

Route types

The following route types are available:

  • System routes — These routes are downloaded from the operating system’s routing table. You cannot to edit or delete these routes from the Kerio Control's UI. They can be removed via SSH using the commands below.
    route del -net IP Address gw Gateway address netmask Mask address dev network system name
  • VPN routes — These routes are visible in the table in the Interfaces column when tunnels are in the Up state. Kerio Control shows all routes configured in IPsec VPN tunnel settings and all routes accessible behind the Kerio VPN tunnel. To create VPN routes, go to the Interfaces section.
  • Static routes — Kerio Control saves static routes to the configuration file and adds them to the system routing table. You can add, modify, remove or temporarily disable these routes.

Modifying static routes in the IPv4 routing table

  1. In the administration interface, go to Routing Table > IPv4 Routing Table.
  2. Click Add.
  3. In the Name field, type the route name.
  4. In the Network field, type an IP subnet.
  5. In the Mask field, type a mask defining the subnet.
  6. In the Interface menu, select the interface.
  7. In the Gateway field, type the IP address of the gateway (if necessary).
  8. In the Metric field, type the number that defines the route's priority.

Modifying routes in the IPv6 routing table

  1. In the administration interface, go to Routing Table > IPv6 Routing Table.
  2. Click Add.
  3. In the Name field, type the route name.
  4. In the Prefix field, type an IP subnet.
  5. In the Prefix length field, type a prefix.
  6. In the Interface menu, select the interface.
  7. In the Gateway field, type the IP address of the gateway (if it is necessary).
  8. In the Metric field, type the number that defines the route's priority.
