Trusted Access
The Moxa PRP/HSR RedBox uses an IP address-based filtering method to control access.
You may add or remove IP addresses to limit access to the Moxa PRP/HSR RedBox. When the accessible IP list
is enabled, only addresses on the list will be allowed access to the Moxa PRP/HSR RedBox. Each IP address and
netmask entry can be tailored for different situations:
•
Grant access to one host with a specific IP address
For example, enter IP address 192.168.1.1 with netmask 255.255.255.255 to allow access to 192.168.1.1
only.
•
Grant access to any host on a specific subnetwork
For example, enter IP address 192.168.1.0 with netmask 255.255.255.0 to allow access to all IPs on the
subnet defined by this IP address / subnet mask combination.
•
Grant access to all hosts
Make sure the accessible IP list is not enabled. Remove the checkmark from
Enable the accessible IP
list
.
