# Nginx ingress controller using Proxy Protocol
For using the Proxy Protocol in a load balancing solution, both the load balancer and its backend need to enable Proxy Protocol.
To enable it for NGINX you have to setup a [configmap](nginx-configmap.yaml) option.
## HAProxy
This HAProxy snippet would forward HTTP(S) traffic to a two worker kubernetes cluster, with NGINX running on the node ports, like defined in this example's [service](nginx-svc.yaml).
```
listen kube-nginx-http
bind :::80 v6only
bind 0.0.0.0:80
mode tcp
option tcplog
balance leastconn
server node1 <node-ip1>:32080 check-send-proxy inter 10s send-proxy
server node2 <node-ip2>:32080 check-send-proxy inter 10s send-proxy
listen kube-nginx-https
bind :::443 v6only
bind 0.0.0.0:443
mode tcp
option tcplog
balance leastconn
server node1 <node-ip1>:32443 check-send-proxy inter 10s send-proxy
server node2 <node-ip2>:32443 check-send-proxy inter 10s send-proxy
```
