I have a pair of CSS 11500 content services switches fronting our IIS web servers farm. On these IIS servers the IIS logs are enabled for our websites. However, when I analyze the IIS logs the client IP is always the IP address of the load balancer, and not the real client IP.
Can anyone help me configure the content switch to send the real IP, or is there some other method which will allow IIS to log the real client IP?
Any advice/pointers would be much appreciated.
If you really have no group command with "add destination service" then the client traffic will go to the server with the client ip as the source. The service won't get any other traffic with the css address except for the keepalive
ip address y.y.y.y
this keepalive request will get to the server with the circuit ip of the CSS as the source.
Before changing the equipment, you should check if you have any "group" in your config.
If your servers are using the CSS as default gateway, those groups could be safely removed and the CSS will stop changing the client ip address.
