Configuring Server Connections
Configuring Servers for Direct Server Return
1. Server configuration for DSR involves these basic steps:
2. Add a loopback network interface on the server.
3. Configure the loopback interface with the IP address and port of the DSR cluster.
4. Edit the configuration of the application on the server to listen for connections on the cluster
IP and port. (An HTTP server, for example, returns a Bad Hostname error to the client if
there is an IP mismatch.)
5. Check the routing on your network to ensure that traffic is being routed as expected. For
example, Equalizer is usually not going to be used as the default gateway on your servers,
since we want the servers to respond to clients directly. In most DSR configurations, the
default gateway used on servers is the gateway most appropriate for reaching the client net-
work. If routes are also needed through Equalizer, they should be configured through static
routes on the servers.
See the Related Topics below for examples of configuring the loopback adapter and an HTTP
server on Windows and Linux platforms for DSR.
