## Add

`gpu_droplets.firewalls.rules.add(strfirewall_id, RuleAddParams**kwargs)`

**post** `/v2/firewalls/{firewall_id}/rules`

To add additional access rules to a firewall, send a POST request to
`/v2/firewalls/$FIREWALL_ID/rules`. The body of the request may include an
inbound_rules and/or outbound_rules attribute containing an array of rules to
be added.

No response body will be sent back, but the response code will indicate
success. Specifically, the response code will be a 204, which means that the
action was successful with no returned body data.

### Parameters

- `firewall_id: str`

- `inbound_rules: Optional[Iterable[InboundRule]]`

  - `ports: str`

    The ports on which traffic will be allowed specified as a string containing a single port, a range (e.g. "8000-9000"), or "0" when all ports are open for a protocol. For ICMP rules this parameter will always return "0".

  - `protocol: Literal["tcp", "udp", "icmp"]`

    The type of traffic to be allowed. This may be one of `tcp`, `udp`, or `icmp`.

    - `"tcp"`

    - `"udp"`

    - `"icmp"`

  - `sources: FirewallRuleTarget`

    An object specifying locations from which inbound traffic will be accepted.

    - `addresses: Optional[List[str]]`

      An array of strings containing the IPv4 addresses, IPv6 addresses, IPv4 CIDRs, and/or IPv6 CIDRs to which the firewall will allow traffic.

    - `droplet_ids: Optional[List[int]]`

      An array containing the IDs of the Droplets to which the firewall will allow traffic.

    - `kubernetes_ids: Optional[List[str]]`

      An array containing the IDs of the Kubernetes clusters to which the firewall will allow traffic.

    - `load_balancer_uids: Optional[List[str]]`

      An array containing the IDs of the load balancers to which the firewall will allow traffic.

    - `tags: Optional[List[str]]`

      A flat array of tag names as strings to be applied to the resource. Tag names must exist in order to be referenced in a request. <br><br>Requires `tag:create` and `tag:read` scopes.

- `outbound_rules: Optional[Iterable[OutboundRule]]`

  - `destinations: FirewallRuleTarget`

    An object specifying locations to which outbound traffic that will be allowed.

    - `addresses: Optional[List[str]]`

      An array of strings containing the IPv4 addresses, IPv6 addresses, IPv4 CIDRs, and/or IPv6 CIDRs to which the firewall will allow traffic.

    - `droplet_ids: Optional[List[int]]`

      An array containing the IDs of the Droplets to which the firewall will allow traffic.

    - `kubernetes_ids: Optional[List[str]]`

      An array containing the IDs of the Kubernetes clusters to which the firewall will allow traffic.

    - `load_balancer_uids: Optional[List[str]]`

      An array containing the IDs of the load balancers to which the firewall will allow traffic.

    - `tags: Optional[List[str]]`

      A flat array of tag names as strings to be applied to the resource. Tag names must exist in order to be referenced in a request. <br><br>Requires `tag:create` and `tag:read` scopes.

  - `ports: str`

    The ports on which traffic will be allowed specified as a string containing a single port, a range (e.g. "8000-9000"), or "0" when all ports are open for a protocol. For ICMP rules this parameter will always return "0".

  - `protocol: Literal["tcp", "udp", "icmp"]`

    The type of traffic to be allowed. This may be one of `tcp`, `udp`, or `icmp`.

    - `"tcp"`

    - `"udp"`

    - `"icmp"`
