Cross-over cabling

To connect a Firebox to a hub or switch, use a standard, straight-through

cable. However, if you plan to connect a Firebox directly to a router, either

purchase or build a cross-over cable for RJ-45 (Cat5) wire.

The tables below provide pin-out descriptions for both a straight-through

and a RJ-45 (Cat5) cross-over cable.

Firebox System Area

WatchGuard ships the Firebox III with a fixed, baseline set of functionality

stored on the read-only system area of the Firebox flash disk memory. It is

possible to start the Firebox using this read-only system area when the

primary user area is misconfigured or corrupted. This functionality

allows you to:

• Troubleshoot problems where all access to the Firebox is lost
