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

Pure IPv6 Server Limitations

Item
Limitation
Agent management
A pure IPv6 server cannot:
  • Deploy agents to pure IPv4 clients
  • Manage pure IPv4 agents.
Updates and centralized management
A pure IPv6 server cannot update from pure IPv4 update sources, such as:
  • Trend Micro ActiveUpdate Server
  • Any pure IPv4 custom update source
Product registration, activation, and renewal
A pure IPv6 server cannot connect to the Trend Micro Online Registration Server to register the product, obtain the license, and activate/renew the license.
Proxy connection
A pure IPv6 server cannot connect through a pure IPv4 proxy server.
Plug-in solutions
A pure IPv6 server will have Plug-in Manager but will not be able to deploy any of the plug-in solutions to:
  • Pure IPv4 agents or pure IPv4 hosts (because of the absence of a direct connection)
  • Pure IPv6 agents or pure IPv6 hosts because none of the plug-in solutions support IPv6.
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 Server and the entities to which it connects or the entities that it serves.
