If your plan is to have a persistant connection to the Internet, regardless of whether you are a SOHO or a large international conglomerate, security is a primary consideration.

From a high-level perspective, one should consider having a dual-homed firewall or even a triple-homed firewall with a DMZ in between with solid transference rules. Typically we will use dual-homed machines pointing toward a second machine as a gateway to insure extra security.

Regardless of the firewall configuration chosen, xDSL provides an inexpensive, quick method of keeping in the fast lane along the information highway.
