Layer 2 Firewall deployment in IPS mode
In an IPS configuration, the Layer 2 Firewalls are installed inline directly in the traffic path.
CAUTION:
Always use standard cabling methods with an inline Layer 2 Firewall. Use crossover cables to connect the appliance to hosts and straight cables to connect the appliance to switches.
