This should be an easy question for firewall experts.
we have a 515e PIX that has 3 Physical interfaces (e0, e1 and e2). I assigned security levels to the interfaces. e0=0 e1=100 e2=10.
We are looking into replacing it with an ASA device.
(1) Which models would provide me with at least those 3 physical interfaces to configure those security zones?. . I get a little confused with some ASA models that come with switch ports integrated.
(2) You might also provide me with some basic "education" about the physical and virtual interfaces on those devices.
