Trend Micro™ Network VirusWall™ Enforcer 1500i (CR100 Series) Installation and Deployment Guide
3-14
Pure IPv6 Environments
In environments with purely IPv6 hosts, administrators do not need to perform special
deployment tasks. As long as Network VirusWall Enforcer is supplied with a valid IPv6
address, it can function normally. Note, however, that certain device features are not
available in pure IPv6 environments as described in
Note:
Many resources on the Internet, including the Trend Micro™ ActiveUpdate™ and
product registration servers, are accessible only through IPv4 traffic. When configured
as an IPv6-only host, Network VirusWall Enforcer traffic to and from the Internet
can be translated using a dual-stack proxy.
Dual-Stack and Mixed Environments
Environments with dual-stack hosts or those with both IPv6 and IPv4 hosts require
relatively complex deployment planning. Consider the following key points during
planning:
•
Ensure that you configure both an IPv4 and IPv6 address for Network VirusWall
Enforcer if it will be processing both kinds of traffic.
•
Network VirusWall Enforcer cannot perform traffic translation when in dual-stack
mode. It will treat IPv6 and IPv4 traffic independently.
•
Note the limitations of the device on IPv6 networks as discussed in
