As an improved security measure you may define what IP addresses are allowed or disallowed access to your domain services. To view a list of IP access rules click on the "IP Access" node for the desired domain.

Reason - The reason access is allowed or denied.
Status - Indicates whether access is allowed or denied.
Access rules are processed in the order listed. For each connection the first matching access rule will be used. Therefore it is important that the access rules be ordered correctly to prevent a user from being mistakenly denied or granted access. You may use the "Up" and "Down" buttons to order these access rules to suit your needs.
To add an access rule click on the "Add" button in the lower right corner. This will display the "New IP access rule" dialog.
