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

Pure IPv6 Security Agent Limitations

Item
Limitation
Parent Apex One server
Pure IPv6 Security Agents cannot be managed by a pure IPv4 Apex One server.
Updates
A pure IPv6 Security Agent cannot update from pure IPv4 update sources, such as:
  • Trend Micro ActiveUpdate Server
  • A pure IPv4 Apex One server
  • A pure IPv4 Update Agent
  • Any pure IPv4 custom update source
Scan queries, web reputation queries, and Smart Feedback
A pure IPv6 Security Agent cannot send queries to smart protection sources, such as:
  • Trend Micro Smart Protection Network (also for Smart Feedback)
Software safety
Pure IPv6 Security Agents cannot connect to the Trend Micro-hosted Certified Safe Software Service.
Plug-in solutions
Pure IPv6 Security Agents cannot install plug-in solutions because none of the plug-in solutions support IPv6.
Proxy connection
A pure IPv6 Security Agent 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 Security Agents and the entities to which they connect.
