## No Port Blocking Policy

<Info>
  OnetSolutions does not block any ports on your VPS, with the exception of outgoing email ports (see below). You have full control over your network configuration.
</Info>

This means you can:

* Run web servers on any port (80, 443, 8080, etc.)
* Receive mail on standard ports (993, 995, 143, 110)
* Set up game servers
* Run any custom application on any port

### Email Ports

<Warning>
  Outgoing email ports (**25**, **465**, **587**) are **blocked by default** on every new VPS to protect our network reputation and prevent abuse.
</Warning>

OnetSolutions does **not allow bulk email sending** from our services (newsletters, marketing campaigns, transactional mailings at scale). For these use cases, please use a dedicated transactional email provider.

If you need to send a reasonable volume of email from your VPS (a personal mail server, application notifications, low-volume transactional email), we can unblock these ports on request, provided:

* You confirm the VPS will **not** be used for bulk email sending
* You agree to comply with our [anti-spam policy](https://onetsolutions.net) and applicable regulations

To request the unblocking, [open a support ticket](https://customer.onetsolutions.net) describing your use case.

## Network Configuration

Your VPS is pre-configured with network settings. To view your current configuration:

<Tabs>
  <Tab title="Debian/Ubuntu">
    ```bash theme={null}
    ip addr show
    ip route show
    ```
  </Tab>

  <Tab title="CentOS/Rocky/Alma">
    ```bash theme={null}
    ip addr show
    ip route show
    ```
  </Tab>

  <Tab title="Windows Server">
    Open Command Prompt and run:

    ```cmd theme={null}
    ipconfig /all
    ```
  </Tab>
</Tabs>

## Firewall Management

<Warning>
  Your VPS has no firewall enabled by default. We strongly recommend configuring firewall rules to protect your server.
</Warning>

You can manage firewall rules through:

1. **Control Panel** - Use the built-in [firewall feature](/vps/firewall) in your OnetSolutions dashboard
2. **Server-side** - Configure `ufw`, `firewalld`, or `iptables` directly on your VPS

## DNS Configuration

To point a domain to your VPS:

<Steps>
  <Step title="Get your VPS IP address">
    Find your IPv4 address in the OnetSolutions control panel or by running `ip addr show` on your server.
  </Step>

  <Step title="Update DNS records">
    Add an A record pointing to your VPS IP address in your domain's DNS settings.
  </Step>

  <Step title="Wait for propagation">
    DNS changes typically propagate within 24-48 hours.
  </Step>
</Steps>
