Hi all, I am wondering how to turn on Proxy Protocol V2 towards the upstream as detailed on

[Accepting the PROXY Protocol | NGINX Documentation](https://docs.nginx.com/nginx/admin-guide/load-balancer/using-proxy-protocol/) under the heading “PROXY Protocol for a TCP Connection to an Upstream”

You can, yes. There are several kong.conf settings that are the same as the underlying NGINX configuration:

> **[Configuration Reference for Kong Gateway - v2.7.x | Kong Docs](https://docs.konghq.com/gateway/2.7.x/reference/configuration/#trusted_ips)**
>
> Documentation for Kong, the Cloud Connectivity Company for APIs and Microservices.

> **[Configuration Reference for Kong Gateway - v2.7.x | Kong Docs](https://docs.konghq.com/gateway/2.7.x/reference/configuration/#proxy_listen)**
>
> Documentation for Kong, the Cloud Connectivity Company for APIs and Microservices.

If you’re using the Helm chart, you won’t configure the `KONG_PROXY_LISTEN` value directly. `proxy_protocol` and other listen parameters are set in the `proxy.http(s).parameters` sections of values.yaml: [https://github.com/Kong/charts/blob/26eff4f94d23f272a64efdfff3a5d109d923b6df/charts/kong/values.yaml#L231-L252](https://github.com/Kong/charts/blob/26eff4f94d23f272a64efdfff3a5d109d923b6df/charts/kong/values.yaml#L231-L252)
