 **Mode** determines how the original client IP is passed through multiple proxies and the way load balancer is set to receive it. It can have two values:
 
-  1. `ProxyProtocol` is a protocol that carries connection information  from the source requesting the connection to the destination for which the connection was requested.

   2. `XForwardedFor` is a multi-value HTTP header that is used by proxies to append IP addresses of the hosts that passed the request.
 
 The choice of mode depends on how the load balancer fronting NGINX Gateway Fabric receives information.
