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:
y
Only 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.
y
Any 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.
y
Any host can access the EDS-518A
Disable this function by deselecting the
Enable the accessible IP list
option.
