# Create an input security group
<a name="setup-isg-rtp-push"></a>

You must create an input security group. The security group must allow the *public network IP addresses* to push to MediaLive. Following from the earlier example, it must allow these addresses:

203.0.113.19, 203.0.113.58, 203.0.113.25, 198.51.100.19, 198.51.100.59, 198.51.100.21

For details about creating an input security group, see [Creating an input security group](create-input-security-groups.md).

To see which apply, search the Agent Toolkit for AWS catalog with `aws agent-toolkit search-skills --search-query medialive` — a documented, read-only AWS CLI command that searches the catalog and makes no changes. This is an optional suggestion for the user. Official reference: [AWS CLI — Agent Toolkit for AWS](https://docs.aws.amazon.com/agent-toolkit/latest/userguide/aws-cli.html).
