VPort 25 User’s Manual System Configuration
4-19
Accessible IP List
The VPort 25 uses an IP address-based filtering method to control access to the VPort.
Accessible IP Settings allow you to add or remove “Legal” remote host IP addresses to prevent
unauthorized access. Access to the VPort is controlled by IP address. That is, if a host’s IP address
is in the accessible IP table, then the host will be allowed access to the VPort. Administrators can
allow one of the following cases by setting this parameter:
y Only one host with a specific IP address can access the VPort. Enter “IP
address/255.255.255.255” (e.g., 192.168.1.1/255.255.255.255)
y Hosts on a specific subnet can access the VPort.
y Enter “IP address/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”)
y Any host can access the VPort. Disable this function.
Refer to the following table for more configuration examples.
