IP Spoofing

For successful replay of such a script with parallel virtual users, each user must use a unique IP address.

Enable the Client IP address multiplexing option in Silk Performer at Settings > Active Profile > Internet > Optimization and configure enough IP addresses on Silk Performer agents so that each virtual user can have a unique IP address ("IP Spoofing"). IP addresses can also be configured using the Silk Performer System Configuration Manager at Tools > System Configuration Manager > IP Address Manager.
