Pure IPv6 Client Limitations

The following table lists the limitations when the client only has an IPv6 address.

Table 1. Pure IPv6 client Limitations

Item

Limitation

Parent Core Protection Module server

Pure IPv6 clients cannot be managed by a pure IPv4 Core Protection Module server.

Updates

A pure IPv6 client cannot update from pure IPv4 update sources, such as:

  • Trend Micro ActiveUpdate Server

  • Any pure IPv4 custom update source

Scan queries, web reputation queries, and Smart Feedback

A pure IPv6 client cannot send queries to smart protection sources, such as:

  • Smart Protection Server 2.0 (integrated or standalone)

    Note:

    IPv6 support for Smart Protection Server starts in version 2.5.

  • Trend Micro Smart Protection Network (also for Smart Feedback)

Software safety

Pure IPv6 clients cannot connect to the Trend Micro-hosted Certified Safe Software Service.

Proxy connection

A pure IPv6 client cannot connect through a pure IPv4 proxy server.

Most of these limitations can be overcome by setting up a dual-stack proxy server that can convert between IPv4 and IPv6 addresses (such as DeleGate). Position the proxy server between the clients and the entities to which they connect.
