Accessible IP
Moxa EtherDevice Switches use an IP address-based filtering method to control access to EDS.
Accessible IP Settings allows you to add or remove Legal remote host IP addresses to prevent
unauthorized access. Access to EtherDevice Switch is controlled by IP addresses. That is, if a
host’s IP address is in the accessible IP table, then the host will be allowed access to the
EtherDevice Switch. You can allow one of the following cases by setting this parameter
y Only one host with the specified IP address can access the EDS-408A/405A
E.g., enter “192.168.1.1/255.255.255.255” to allow access to just the IP address 192.168.1.1.
y Any host on a specific sub network can access the EDS-408A/405A
E.g., enter “192.168.1.0/255.255.255.0” to allow access to all IPs on the sub network defined
by this IP address/netmask combination.
y Any host can access the EDS-408A/405A
Disable this function by not selecting the Enable the accessible IP list checkbox.
