A pure IPv6 client cannot
               update directly from pure IPv4 update sources, such as:
            
            
               - 
                  
A pure IPv4 OfficeScan server
                  
                
               - 
                  
A pure IPv4 Update Agent
                
               - 
                  
Any pure IPv4 custom update source
                
               - 
                  
Trend Micro ActiveUpdate Server
                
            
            Similarly, a pure IPv4 client cannot
               update directly from pure IPv6 update sources, such as a pure IPv6 OfficeScan server or Update Agent.
            
            A dual-stack proxy server that can convert IP addresses, such
               as DeleGate, is required to allow the clients to connect
               to the update sources.
