+
+Now go to the "Security policies" tab, and click on "New IOC Feed"
+
+![](/img/checkpoint_step3.png)
+
+Click on "Custom Policy", then below on "Indicators". Add your feed information and click "Test Feed".
+
+You need to put the username and password provided by the console in the "Feed URL" so it can use basic authentication:
+
+```
+https://<username>:<password>@admin.api.crowdsec.net/v1/integrations/<integration_id>/content
+```
+
+In this example, we used "Generic Firewall Format", but you can use checkpoint format and select the data column "1".
+

+
+Select the Gateway and click "Test Feed"
+
+![](/img/checkpoint_step5.png)
+
+Check That the feed is working and save the configuration.
