**PLEASE NOTE**: Algo is intended for use as a _dedicated_ VPN server. If you install Algo on an existing server, then any existing services might break. In particular, the firewall rules will be overwritten. See [AlgoVPN and Firewalls](/docs/firewalls.md) for more information.
If you don't want to overwrite the rules you must deploy via `ansible-playbook` and skip the `iptables` tag as described in [deploy-from-ansible.md](deploy-from-ansible.md), after which you'll need to implement the necessary rules yourself.
