How to Add a Static Route to Kemp Loadmaster

Often clients and Real Servers need to be reached on networks via gateways other than the LoadMaster Default Gateway (for example when the LoadMaster is sitting in a DMZ network and needs to reach internal subnets). A static route tells the LoadMaster the IP address of the correct route to use for a particular subnet or host.

To create a static route, follow the steps below in the LoadMaster Web User Interface (WUI):

  1. Go to System Configuration > Network Setup > Additional Routes.
  2. Define the new route. The Destination should be the subnet or host definition that the LoadMaster needs to contact. The Gateway should be the IP address of a gateway router on a network that the LoadMaster is connected to that can route traffic to the Destination.


A LoadMaster has eth0 connected to the subnet with a default gateway of and needs to communicate to the network which is reachable over a Multiprotocol Label Switching (MPLS) connection controlled by the MPLS router

The static route that needs to be configured would have the following settings:

  • Destination =
  • Gateway =

Note: Ensure to include the Classless Inter-Domain Routing (CIDR) subnet notation (i.e. /24) in subnet definitions, otherwise the LoadMaster will automatically assign a /32 value to the route.
