Spoof

When the Spoof option is enabled on a cluster, Equalizer uses the client’s

IP address as the source IP address in all packets sent to a server in that

cluster.

When Spoof is enabled, all server responses to client requests that came

through the Equalizer cluster IP address must be routed by the server

back to the client through Equalizer. In many cases, the easiest way to do

this is to set the default gateway on the server instances in the server pool

on a cluster to Equalizer’s IP address on the server VLAN. If this is not

possible, you can establish static routes on the server to send responses

to specific client IP addresses to Equalizer’s IP address on the VLAN.

If you disable Spoof, the server receiving the request will see Equalizer’s

IP address as the client address because the TCP connection to the client is

terminated when the request is routed. The server will therefore send its

response back to Equalizer’s IP address.

When the Spoof flag is disabled on a Layer 4 cluster:

If there is more than one VLAN defined, all server instances on a server

pool must be located on the second defined VLAN in the configuration (the

VLAN that appears after the Default VLAN in the GUI, in ifconfig output,

and in the configuration file), so that source NAT will work correctly. This

is because the source IP address used when spoof is disabled is the

Equalizer IP address on that VLAN.

TCP Cluster Persistence

The TCP Cluster Configuration Persistence screen is used to configure Sticky Netmask values, Timeouts and

assign the Inter Cluster sticky flag to the selected TCP cluster. It can be accessed by selecting a cluster from the

left navigational pane and selecting the Configuration > Persistence tabs.
