# AWS::GameLift::ContainerFleet IpPermission
<a name="aws-properties-gamelift-containerfleet-ippermission"></a>

A range of IP addresses and port settings that allow inbound traffic to connect to processes on an instance in a fleet. Processes are assigned an IP address/port number combination, which must fall into the fleet's allowed ranges. 

For Amazon GameLift Servers Realtime fleets, Amazon GameLift Servers automatically opens two port ranges, one for TCP messaging and one for UDP.

## Syntax
<a name="aws-properties-gamelift-containerfleet-ippermission-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-gamelift-containerfleet-ippermission-syntax.json"></a>

```
{
  "[FromPort](#cfn-gamelift-containerfleet-ippermission-fromport)" : {{Integer}},
  "[IpRange](#cfn-gamelift-containerfleet-ippermission-iprange)" : {{String}},
  "[Protocol](#cfn-gamelift-containerfleet-ippermission-protocol)" : {{String}},
  "[ToPort](#cfn-gamelift-containerfleet-ippermission-toport)" : {{Integer}}
}
```

### YAML
<a name="aws-properties-gamelift-containerfleet-ippermission-syntax.yaml"></a>

```
  [FromPort](#cfn-gamelift-containerfleet-ippermission-fromport): {{Integer}}

`FromPort`  <a name="cfn-gamelift-containerfleet-ippermission-fromport"></a>
A starting value for a range of allowed port numbers.  
For fleets using Linux builds, only ports `22` and `1026-60000` are valid.

`IpRange`  <a name="cfn-gamelift-containerfleet-ippermission-iprange"></a>
A range of allowed IP addresses. This value must be expressed in CIDR notation. Example: "`000.000.000.000/[subnet mask]`" or optionally the shortened version "`0.0.0.0/[subnet mask]`".  
*Required*: Yes  
*Type*: String  
*Pattern*: `(^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])(/([0-9]|[1-2][0-9]|3[0-2]))$)`

`ToPort`  <a name="cfn-gamelift-containerfleet-ippermission-toport"></a>
An ending value for a range of allowed port numbers. Port numbers are end-inclusive. This value must be equal to or greater than `FromPort`.  
For fleets using Linux builds, only ports `22` and `1026-60000` are valid.  
For fleets using Windows builds, only ports `1026-60000` are valid.
