# HAProxy Rules for the Fixed IPv4 Provider

In case I don't have a fixed IPv4 address, I use these rules to route the services through a fixed IPv4 provider like Oracle Cloud.

## Pre-Requesites

* Install HAProxy on the server : `sudo dnf install -y haproxy`
* Copy the configuration file: `sudo cp /home/opc/bin/NAT/haproxy.cfg /etc/haproxy/haproxy.cfg`
* Enable the service: `sudo systemctl enable --now haproxy`
* Open the ad-hoc ports (bound from haproxy.cfg) in the firewall, for instance: `sudo firewall-cmd --add-port=80/tcp --permanent`
