Real Server Forwarding Methods

 

Information

 

Summary:

This article will discuss real server forwarding methods and how they interact with different features on the LoadMaster.

Environment:

Product: Loadmaster

Version: Any

Platform: Any

Application: Any

Question/Problem Description:

Will the NAT forwarding method interfere with Transparency?

Steps to Reproduce:  
Error Message:  
Defect Number:  
Enhancement Number:  
Cause:  
Resolution:

Within Virtual Services > View/Modify Services > modify your existing Virtual Service > SubVSs (if applicable) > Real Servers, each Real Server is configured with a Forwarding Method. Typically, this Forwarding Method is NAT. The NAT forwarding method is the default and will not interfere with Transparency or any other feature designed to pass on the source IP of the connection to the real server. This would be the job of a proxy, which Transparency is in direct opposition to.

The alternative to the NAT Forwarding method is Direct return, which is required for Direct Server Return, as outlined in the below article.
