## Deployment Recommendations

### Allow port access for Firewalls

By default MinIO uses the port 9000 to listen for incoming connections. If your platform blocks the port by default, you may need to enable access to the port.

### ufw

For hosts with ufw enabled (Debian based distros), you can use `ufw` command to allow traffic to specific ports. Use below command to allow access to port 9000

```sh
ufw allow 9000
```
