Exhibit 2

A company has an Aruba solution. Client 1 is assigned to the users1 role, and client 2 is assigned to the users2 role. The exhibits show current firewall rules for those roles. The network1 alias used to be 10.1.1.0/24, but the network administrator now changes the network1 alias to 172.16.1.0/24. Client 1 and Client 2 both send a packet destined to 172.16.1.10.
