On a wildcard load
balancing virtual server if you explicitly configure a route to a destination,
by default, the NetScaler appliance forwards traffic according to the
configured route. If you want the NetScaler to not look up for the configured
route, you can set the Prefer Direct Route option to NO.
If a device is
directly connected to a NetScaler appliance, the NetScaler directly forwards
traffic to the device. For example, if the destination of a packet is a
firewall, the packet need not be routed through another firewall. However, in
some cases, you may want the traffic to go through the firewall even if the
device is directly connected to it. In such cases, you can set the Prefer
Direct Route Option to NO.
preferDirectRoute setting is applicable to all the wildcard virtual servers on
the NetScaler appliance.
