Before you beginRole required: admin Procedure Navigate to System Security > IP Address Access Control to see a list of your IP access controls. You may need to activate this module. You can add these types of rules: Allow: any IP address in this range is allowed to connect to this instance. Deny: any IP address in this range is not allowed to connect to this instance unless it is listed in an allow rule. Note: These rules also affect transferring update sets.
