IP Spoofing

It is a technique used for creating Internet Protocol (IP) packets with a forged source IP address, with the purpose of hiding the identity of the sender address.

IP Spoofing in Loadrunner

This technique is used in Loadrunner Agent machines, in order to make the Application server to think requests are coming from different machines. This purposely used in the Load Balancing Application servers which runs on the IP based distribution.

Procedures to configure the IP Spoofing in Loadrunner

Step 01: Get the required number of static IPs (based on number of vusers to be executed) from the Network Administrator, which should have the same ‘Default gateway’ of the LG machine.

Step 02: Follow the IP wizard in the LG machine and do the setup by adding the required number of Static IPs.

Step 03: After finishing the configuration setup, try pinging one of the static IP. It should not get ‘Timed Out’ error.

Step 04: Now we are ready to do the execution with Controller. While creating the scenario, enable the ‘IP Spoofing’ option in the LG machine.

This should work. If any issues, comment to reach me. Thanks.
