Trend Micro™ Network VirusWall™ Enforcer 1500i (CR100 Series) Installation and Deployment Guide
3-18
Network VirusWall Enforcer protects your network as follows:
•
Scans traffic to and from endpoints
•
Prevents endpoints that violate your security policies from gaining access to
resources
•
Isolates endpoints in the event of a virus infection
In this deployment setup, you may opt to enable failopen. With failopen enabled, traffic
can still pass through the device if the device encounters a hardware or system error that
prevents it from filtering network packets.
Failopen Considerations
Consider the following points when using failopen mode:
•
All regular ports (ports 3 and 4) on the device support LAN bypass and will allow
traffic to pass when the device is powered off.
•
The total length of the network cable connecting a regular port to other devices
must not exceed 100 meters (328 feet) for copper port connections.
Note:
This constraint only applies to failopen deployments. The network cable should
not exceed 50 meters. A cable that is longer than the maximum length will
prevent failopen from working, because the natural electrical resistance of copper
wire significantly weakens the signal.
