Using Equalizer E250GX in a Single Network Environment
In single network mode, the client systems, servers, Intranet and/or Internet must all connect to Equalizer through
the Internal Interface Port. Figure 7 shows an example.
Figure 7 Example single network configuration for Equalizer E250GX
Single network mode is often the simplest way to fit Equalizer into an existing network with minimal changes to the
current network infrastructure. Certain protocols and applications that use dynamic port mapping or multiple TCP/
UDP ports may also work best in a single network environment.
As you can see in the example above, Equalizer’s internal IP, cluster IP, and all server IPs are located on the
192.168.0.x network, and communicate through the same switch. The switch, in turn, is connected to a router which
is this subnet’s gateway to other subnets on the Intranet and Internet networks. The gateway or router that conects
Equalizer’s subnet to the Intranet and Internet is assumed to perform all necessary NAT for external clients, so they
can access Equalizer’s cluster IPs.
Internal clients can access the cluster IPs directly, and so may require selective SNAT on Equalizer or special routing
on the servers to ensure that all server responses go through Equalizer.
