Extend your LAN to include more sub-networks
Updated: June 9, 2010
Applies To: Windows Server 2008, Windows Server 2008 R2
You can use the goals below to extend your local area network to include more subnets.
Create a new subnet and provide communications flow for network traffic between the new subnet and the existing subnet
Automatically assign IPv4 addresses to computers on a new subnet
Automatically assign IPv6 addresses to computers on a new subnet
Create a new subnet and provide communications flow for network traffic between the new subnet and the existing subnet
To accomplish this goal, you need to deploy Routing and Remote Access Service as a router. For more information, see Checklist: Installing and Configuring an RRAS Router at https://go.microsoft.com/fwlink/?LinkId=193988.
Automatically assign IPv4 addresses to computers on a new subnet
To accomplish this goal, you must do one of the following:
Deploy a Dynamic Host Configuration Protocol (DHCP) server on the new subnet. For more information, see Deploying DHCP Server at https://go.microsoft.com/fwlink/?LinkId=193985.
Use an existing DHCP server on the first subnet to assign IP addresses to computers on the new subnet by creating a new DHCP scope and enabling DHCP relay agent on the router that connects the subnets. For more information, see Dynamic Host Configuration Protocol at https://go.microsoft.com/fwlink/?LinkID=117634.
Automatically assign IPv6 addresses to computers on a new subnet
To accomplish this goal, you need to deploy a DHCP server that is configured to assign IPv6 addresses. For more information, see The DHCPv6 Protocol at https://go.microsoft.com/fwlink/?LinkId=193993.
