To create a new security rule, navigate to Publications > Settings > Security Rules and select Add.
This article will cover the security rule IP Address:
All networks have a unique IP address and, in most cases, businesses will have fixed IP addresses for their networks.
By specifying IP addresses in your security rules, you are restricting the networks that have access to your publication.
This setting is useful when you want to restrict access to your offices/sites or intranet.
If you do not specify any IP addresses, all networks will be able to access your publication (providing they meet other security requirements).
To add an IP address to the list, paste the IP address into the New IP Address field and select Add.
If you need to delete an IP address select it from the Current IP Address field and click the Delete Selected button.
