Accessible IP

MOXA EDS-518A uses an IP address-based filtering method to control access to EDS-518A units.

Accessible IP Settings allows you to add or remove “Legal” remote host IP addresses to prevent unauthorized access. Access to EDS-518A is controlled by IP address. If a host’s IP address is in the accessible IP table, then the host will be allowed access to the EDS-518A. You can allow one of the following cases by setting this parameter:

yOnly one host with the specified IP address can access the EDS-518A

E.g., enter “192.168.1.1/255.255.255.255” to allow access to just the IP address 192.168.1.1.

yAny host on a specific subnetwork can access the EDS-518A

E.g., enter “192.168.1.0/255.255.255.0” to allow access to all IPs on the subnet defined by this IP address/subnet mask combination.

yAny host can access the EDS-518A

Disable this function by deselecting the Enable the accessible IP list option. The following table shows additional configuration examples:
