Weak and Strong Host Behavior in Windows for multihomed Computer

Weak and Strong Host Behavior in Windows
Windows XP and Windows Server® 2003 use the weak host model for sends and receives for all IPv4 interfaces and the strong host model for sends and receives for all IPv6 interfaces. You cannot configure this behavior. The Next Generation TCP/IP stack in Windows Vista and Windows Server 2008 supports strong host sends and receives for both IPv4 and IPv6 by default on all interfaces except the Teredo tunneling interface for a Teredo host-specific relay. Figure 4 lists the commands that you can use to configure send and receive behavior for both IPv4 and IPv6 on a per-interface basis. Note that InterfaceNameOrIndex is either the name of the interface from the Network Connections folder or its interface index. You can obtain the interface index of an interface from the display of the command:
 
 Commands to configure strong and weak send and receive behavior

• netsh interface ipv4 set interface [InterfaceNameOrIndex] weakhostsend=enabled|disabled
• netsh interface ipv4 set interface [InterfaceNameOrIndex] weakhostreceive=enabled|disabled
• netsh interface ipv6 set interface [InterfaceNameOrIndex] weakhostsend=enabled|disabled
• netsh interface ipv6 set interface [InterfaceNameOrIndex] weakhostreceive=enabled|disabled
 

netsh interface ipv6 show interface
