STEP 2 Install and Configure ROUTER1

Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016

In this multisite test lab guide, the router computer provides an IPv4 and IPv6 bridge between the Corpnet and 2-Corpnet subnets, and acts as a router for IP-HTTPS and Teredo traffic.

  • Install the operating system on ROUTER1

  • Configure TCP/IP properties and rename the computer

  • Turn off the firewall

  • Configure routing and forwarding

Install the operating system on ROUTER1

  4. Click Internet Protocol Version 4 (TCP/IPv4), and then click Properties.

  5. Click Use the following IP address. In IP address, type 10.0.0.254. In Subnet mask, type 255.255.255.0, and then click OK.

  6. Click Internet Protocol Version 6 (TCP/IPv6), and then click Properties.

  7. Click Use the following IPv6 address. In IPv6 address, type 2001:db8:1::fe. In Subnet prefix length, type 64, and then click OK.

  8. On the Corpnet Properties dialog box click Close.

  9. In the Network Connections window, right-click the network adapter that is connected to 2-Corpnet, click Rename, type 2-Corpnet, and press ENTER.

  10. Right-click 2-Corpnet, and then click Properties.

  11. Click Internet Protocol Version 4 (TCP/IPv4), and then click Properties.

  13. Click Internet Protocol Version 6 (TCP/IPv6), and then click Properties.

  14. Click Use the following IPv6 address. In IPv6 address, type 2001:db8:2::fe. In Subnet prefix length, type 64, and then click OK.

  15. On the 2-Corpnet Properties dialog box click Close.

  16. Close the Network Connections window.

  17. In the Server Manager console, in Local Server, in the Properties area, next to Computer name, click the link.

  18. On the System Properties dialog box, on the Computer Name tab, click Change.

  19. On the Computer Name/Domain Changes dialog box, in Computer name, type ROUTER1, and then click OK.

  20. When you are prompted that you must restart the computer, click OK.

  21. On the System Properties dialog box, click Close.

  22. When you are prompted to restart the computer, click Restart Now.

  23. After the computer has restarted, log on with the local Administrator account.

Turn off the firewall

This computer is configured only to provide routing between the Corpnet and 2-Corpnet subnets; therefore, the firewall must be turned off.

To turn off the firewall

  1. On the Start screen, typewf.msc, and then press ENTER.

  2. In Windows Firewall with Advanced Security, in the Actions pane, click Properties.

  3. On the Windows Firewall with Advanced Security dialog box, on the Domain Profile tab, in Firewall state, click Off.

  5. On the Windows Firewall with Advanced Security dialog box, on the Public Profile tab, in Firewall state, click Off, and then click OK.

  6. Close Windows Firewall with Advanced Security.

Configure routing and forwarding

To provide routing and forwarding services between the Corpnet and 2-Corpnet subnets, you must enable forwarding on the network interfaces and configure static routes between the subnets.

To configure static routes

  1. On the Start screen, typecmd.exe, and then press ENTER.

  2. Enable forwarding on both the IPv4 and IPv6 interfaces of both network adapters using the following commands. After entering each command, press ENTER.

    netsh interface IPv4 set interface Corpnet forwarding=enabled
    netsh interface IPv4 set interface 2-Corpnet forwarding=enabled
    netsh interface IPv6 set interface Corpnet forwarding=enabled
    netsh interface IPv6 set interface 2-Corpnet forwarding=enabled
    
  3. Enable IP-HTTPS routing between the Corpnet and 2-Corpnet subnets.

    netsh interface IPv6 add route 2001:db8:1:1000::/59 Corpnet 2001:db8:1::2
    netsh interface IPv6 add route 2001:db8:2:2000::/59 2-Corpnet 2001:db8:2::20
    
  4. Enable Teredo routing between the Corpnet and 2-Corpnet subnets.

    netsh interface IPv6 add route 2001:0:836b:2::/64 Corpnet 2001:db8:1::2
    netsh interface IPv6 add route 2001:0:836b:14::/64 2-Corpnet 2001:db8:2::20
    
  5. Close the Command Prompt window.
