IP Access tab

The IP Access tab allows to set up IP access rules applied to incoming requests. There are two types of IP access rules: Allow and Deny rules. A request with an IP address matching an Allow rule will be passed on to examination with the next rule in order; a request with an IP matching a Deny rule will be discarded immediately. Requests passing all rules will be finally delivered for further processing.

If IP access restriction is enabled, each rule will be checked against the incoming request's IP in top-down order until it has a match. If no match is found, the request is denied. Remember to add a final rule to allow all traffic (*.*.*.*) if there is no Allow rule.

Check Enable IP access restriction for this server to edit the following: field box, add allow, add deny, edit, remove, up and down.

The field box should not be empty or include characters; it should contain a valid IP or mask, such as Single IP (192.168.0.100), IP range (192.168.0-100.1), IP/inverse masks(192.168.0.0/0.0.0.255), CIDR format (192.168.0.0/24), or Wildcard mask (192.168.*.100-200).
