Creating IP Access Control Rules
IP access control rules (firewall rules) determine whether to accept or discard traffic to/from the 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 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.
•
Subnet mask is required.
When typing the IP address, you must specify BOTH the address and a subnet mask. For example, to specify a single
address in a Class C network, use this format:
x.x.x.x/24
where
/24
= a subnet mask of 255.255.255.0.
To specify an entire subnet or range of addresses, change the subnet mask accordingly.
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.
Go to the Inbound Rules section or the Outbound Rules section according to your needs.
