NE-4100 has an IP address based filtering method to control access to the NE-4100.
Accessible IP Settings allows you to add or remove “Legal” remote host IP addresses to prevent
unauthorized access. Access to NE-4100 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 NE-4100. You can allow
one of the following cases by setting the parameter.
# Only one host with a specific IP address can access the NE-4100
Enter “IP address/255.255.255.255” (e.g., “192.168.1.1/255.255.255.255”).
# Hosts on a given subnet can access the NE-4100
Enter “IP address/255.255.255.0” (e.g., “192.168.1.0/255.255.255.0”).
# Any host can access the NE-4100
Disable this function. Refer to the following table for more details about the configuration
example.
