Get ClientIP Address Behind LoadBalancer

 

Just for an example, our piece of code has captured a customer IP address as 86.1.65.146, however the tool has captured the same as 2.103.197.20, which seems to be correct.

 

 

 

I'm a little confused now. Can you please verify that:

 

 

1. The client's TRUE IP address is available to the F5 as the request accesses the virtual server, and

 

 

2. A TCPDUMP between the F5 and the server, shows or does not show an HTTP header (either XFF or custom) with that same client IP address.

 

 

That TCPDUMP will show what you're getting at the server. How you process that information is another matter, and I would first like to assess that the F5 is sending the information.

 

 

Also, how are you configuring the F5 to send the client IP? XFF setting in HTTP profile or iRule?
