Creating Firewall Rules
Firewall rules accept or drop traffic intended for the ePDU, based on the IP address of
the host sending the traffic. When creating firewall rules, keep the following in mind:
S
Rule order: The order of the rules is important. When traffic reaches the ePDU, the
rules are executed in numerical order. The first rule that matches the IP address
determines whether the traffic is accepted or dropped. Any subsequent rules
matching the IP address have no effect on the traffic
S
Subnet mask: 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.
To create firewall rules:
1. Select Device Settings , and then select Security . The Security Settings page
displays. The panel at the upper right is labeled IP Access Control . This controls
the firewall.
2. Select the Enable IP Access Control check box if it is not already selected.
3. Follow the steps listed in Table 3 to create specific rules.
