The alias in the rule shown in the exhibit is network 10.1.1.0/24.
A wireless client is assigned IP address 10.1.2.10/24 and the "admins" role. The wireless client at
10.1.2.10 attempts to initiate a Web session with a server at 10.1.1.2. a wired client at 10.1.1.3 attempts to
initiate an SSH session with the wireless client at 10.1.2.10.
How does the Aruba firewall handle these attempts?
