Creating IP Access Control Rules
IP access control rules (firewall rules) determine whether to accept or discard traffic to/from the Legrand
PDU, based on the IP address of the host sending or receiving the traffic. When creating rules, keep these
principles in mind:
Rule order is important.
When traffic reaches or is sent from the Legrand PDU, the rules are executed in numerical order. Only
the first rule that matches the IP address determines whether the traffic is accepted or discarded. Any
subsequent rules matching the IP address are ignored.
