IP Mask - The IP address mask.

Access - Indicates whether access is allowed or denied.

Reason - The reason 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.
