I have a DSL line and a Cisco PIX 501 firewall.

Can I connect the DSL line directly to the PIX (and then have a switch behind the PIX for clients to connect through)?  Or, do I need to connect the DSL line to a router, then connect the router to the PIX?

PIX 501 / DLS connection

Software firewalls, also known as host-based firewalls, provide a layer of software on one host that controls network traffic in and out of that single machine. Most operating systems now include firewall software, but many available software firewalls include central distribution, antivirus systems and disaster recovery.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not.
