iRule for REMOTE_ADDR

Hi,

 

 

Are you wanting to log the value in the X-Forwarded-For value or actually use the value in generating the HTML content? If the former, you can use a DLL plugin to log the value. Else, it would probably be easier to modify the scripts running on the servers to parse the value. You could either disable the SNAT or use an iRule to take the XFF value and use it as the source IP in traffic sent to the pool. Either of the last two options would require that the default gateway on the pool members be set to the floating IP of the BIG-IP.

 

 

Can you clarify what you're trying to do and whether you can set the default gateway of the pool members to the BIG-IP's self IP?

 

 

Thanks,

 

Aaron
