XFF When Using DNS Proxy Object

L4 Transporter

Hi All,

 

I am using DNS proxy and as such all the threat logs that are to do with DNS requests only have the firewall IP in them, all users are using Global Protect and I have enabled x-forwarded-for headers for user-id.

 

Is there anything else that I need to do or is this unsupported ?

 

 

Thank you in advance,

@laurence64,

I don't think you're going to get that to work as you are hoping. DNS Proxy is going to show the firewall making the actual DNS request if the request doesn't exist in its cache. The x-forwarded-for header isn't going to come into play in that aspect.

Absolutely! I have tried everything I can think of, I guess it is just through the reporting that we can see who is making calls to the Sinkhole address, we do have XSOAR so URL reporting and alerting is instant but it would have been nice to have it reflected in the logs.
