NimbostratusF5 IIS 10 Original c-ip - x-forwarded-for
Greetings everyone, We have a F5 LB who is handling all the load for our web servers. But there is a problem when reading the IIS logs for the original client ip ( we have SNAT that shows the virtual IP instead of client ip).
So far i have only found that IIS 10 supports enhanced logging and you can set your own input for x-forwarded-for. My question is, if we enable x-forwarding-for in the F5 - Services - HTTP and add the enhanced loggin for IIS10 custom field - can we get the original client ip ?
Sorry if this is posted before but i couldn't find the question.
Thanks forward. Z.

That setting actually does that...insert the X-Forwarded-for header with the original IP so it will be available to your IIS server.

In the next article is described how to add X-Forwarder-For Header to the site logs:
