XFF: For security Policy

L4 Transporter

Trying to implement this.

Azure Web Application Gateway is in the front, acting as proxy. I can see packet captures for port 80 x-forward for is included

But i don't see xff in traffic logs, and matching the url accessed shows traffic from Azure Gateways internal backend IP and not from the original client IP in XFF.

How ever I don't see IP under XFF traffic logs as source ip

Also i tried adding source ip to be blocked to test, and could not get it to work

Thanks @nikoolayy1 

Rewriting HTTP header on Application Gateway to remove port information made it work.
