You can configure [cloud-managed firewall](https://hostman.com/cloud-firewall/) rules when creating a new firewall or when editing an existing firewall.

## Creating New Rules

> [!NOTE]
> If the **Allow traffic** option is selected, only traffic that matches the rule will be allowed. All other traffic will be blocked.
>
> If the **Deny traffic** option is selected, all traffic will be allowed except traffic specified by the rules.

### For a New Firewall

To create a new rule when creating a new firewall:

1.  Choose what you want to do: allow or deny certain traffic.

3.  Specify the parameters:
    

-   -   **Subnet or address**. You can specify a specific IP, subnet, or the value `0.0.0.0/0` to allow/deny all addresses and subnets, or you can select **For all addresses**.
        
    -   **Type**. You can set your own rule or choose one of the ready-made types. In this case, the protocol and port will be filled in automatically.
        
    -   **Protocol**. You can select TCP, UDP or ICMP.
        
    -   **Port**. You can specify a port or a range of ports.
        

4.  Click **Add**.
