You're viewing documentation for the legacy version of Firezone, now End-of-Life. View the latest docs here.
Security considerations
Disclaimer: Firezone is still beta software. The codebase has not yet received a formal security audit. For highly sensitive and mission-critical production deployments, we recommend disabling local authentication as detailed below.
List of services and ports
Shown below is a table of default ports used by Firezone services.
| Service | Port | Listen address | Description |
|---|---|---|---|
| Caddy | 443/tcp | all | Public HTTPS port for administering Firezone and facilitating authentication. |
| Caddy | 80/tcp | all | Public HTTP port used for ACME. Disabled when ACME is disabled. |
| WireGuard | 51820/udp | all | Public WireGuard port used for VPN sessions. |
| Postgresql | 5432/tcp | - | Containerized port used for bundled Postgresql server. |
| Phoenix | 13000/tcp | - | Containerized port used by upstream elixir app server. |
| Service | Port | Listen address | Description |
|---|---|---|---|
| Nginx | 443/tcp | all | Public HTTPS port for administering Firezone and facilitating authentication. |
| Nginx | 80/tcp | all | Public HTTP port used for ACME. Disabled when ACME is disabled. |
| WireGuard | 51820/udp | all | Public WireGuard port used for VPN sessions. |
| Postgresql | 15432/tcp | 127.0.0.1 | Local-only port used for bundled Postgresql server. |
| Phoenix | 13000/tcp | 127.0.0.1 | Local-only port used by upstream elixir app server. |
Production deployments
For production deployments of Firezone, we recommend you disable local
authentication altogether by setting
default['firezone']['authentication']['local']['enabled'] = false
(Omnibus-based deployments) or LOCAL_AUTH_ENABLED=false (Docker-based
deployments). Local authentication can also be disabled on the
/settings/security page.
Ensure you've set up a working OIDC or SAML-based authentication provider before disabling the local authentication method.
