Prefix length is required.
When typing the IP address, you must specify it in the CIDR notation. That is, BOTH the address and the
prefix length are included. For example, to specify a single address with the 24-bit prefix length, use this
format:
x.x.x.x/24
/24
= the prefix length.
Note: Valid IPv4 addresses range from 0.0.0.0 through 255.255.255.255.
To configure IPv4 access control rules:
1. Choose Device Settings > Security > IP Access Control.
2. Select the 'Enable IPv4 access control' checkbox to enable IPv4 access control rules.
3. Determine the IPv4 default policy.
Accept: Accepts traffic from all IPv4 addresses.
Drop: Discards traffic from all IPv4 addresses, without sending any failure notification to the source
host.
Reject: Discards traffic from all IPv4 addresses, and an ICMP message is sent to the source host for
failure notification.
4. Go to the Inbound Rules section or the Outbound Rules section according to your needs.
Inbound rules control the data sent to the Legrand PDU.
Outbound rules control the data sent from the Legrand PDU.
