I am currently looking into the Cisco ASA firewalls.  Mainly the 5520-5540.  The firewall has 4 - ethernet ports.  None of them being labled internal or external.  Do these devices give the ability to configure any of these ports as any internal/external/DMZ?  I've been sufing thru the site trying to find info on all this and so far I've been unable to find expliation on the "ports" and their usage.

ASA 5520-5540

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
