IP Filtering

The IP ﬁltering function keeps unauthorized hosts from accessing the Console Server by

specifying rules.

The IP address/mask speciﬁes the host range by entering the base host IP address followed

by “/” and the subnet mask (“/” is a required separator between the IP address and the

subnet mask). The host IP addresses are ﬁltered based on the rule deﬁned.

The table below provides examples of IP address/mask settings.

The “Port” is a port or port range of the Console Server to which hosts try to access.

ChainRule

The chain rule determines whether the access from the hosts is allowed or not. It can be one

of two values:

• ACCEPT: access allowed

• DROP:access not allowed
