1. The out of the box setup is 2 ports. These are user configurable as WAN and LAN?
2. To add a DMZ and have other devices behind the firewall, I would add a PIX-4FE-66 card?
3. 99% of the traffic will be web users to the a shopping site. At most 4 VPN users to an internal server. In the future I would want to implement failover. Is this a suitable solution or are there better cost effective options? This will be in a colocated environment.
