USING THE WEB INTERFACEEATON Managed ePDU User’s Guide 164201xxx Rev 1 DRAFT 10−OCT−2008 41Creating Firewall RulesFirewall rules accept or drop traffic intended for the ePDU, based on the IP address ofthe host sending the traffic. When creating firewall rules, keep the following in mind: Rule order: The order of the rules is important. When traffic reaches the ePDU, therules are executed in numerical order. The first rule that matches the IP addressdetermines whether the traffic is accepted or dropped. Any subsequent rulesmatching the IP address have no effect on the traffic Subnet mask: When typing the IP address, you MUST specify both the addressand a subnet mask. For example, to specify a single address in a Class C network,use this format:x.x.x.x/24where /24 = a subnet mask of 255.255.255.0.To specify an entire subnet or rangeof addresses, change the subnet mask accordingly.To create firewall rules:1.
