# Optional Configuration

You can set these environment variables to configure the container. They are not required, but can be useful in some cases.

Env | Default | Example | Description
--- | --- | --- | ---
`PORT` | `51821` | `6789` | TCP port for Web UI.
`HOST` | `0.0.0.0` | `localhost` | IP address web UI binds to.
`INSECURE` | `false` | `true` | If access over http is allowed
`DISABLE_IPV6` | `false` | `true` | If IPv6 support should be disabled

IPv6 Caveats

Disabling IPv6 will disable the creation of the default IPv6 firewall rules and won't add a IPv6 address to the interface and clients.

You will however still see a IPv6 address in the Web UI, but it won't be used.

This option can be removed in the future, as more devices support IPv6.
