Routing and Remote Access Service (RRAS) is a Microsoft API and server software that allows an administrator to configure dial-up remote access servers, VPN servers, and IP routing. It's a crucial component for organizations that need to provide secure remote access to their network resources. This article will guide you through the steps to set up RRAS on a Windows Server environment, ensuring that you can manage remote connections and routing efficiently.

Examples:

1. Installing RRAS via Server Manager:

   • Open Server Manager.
   • Click on Manage and then Add Roles and Features.
   • In the Add Roles and Features Wizard, click Next until you reach the Select server roles page.
   • Check the box for Remote Access and click Next.
   • On the Select features page, click Next.
   • On the Remote Access page, click Next.
   • On the Select role services page, check the box for Routing and DirectAccess and VPN (RAS), then click Next.
   • Click Install and wait for the installation to complete.

2. Configuring RRAS:

   • Open Server Manager.
   • Click on Tools and then Routing and Remote Access.
   • In the RRAS management console, right-click on your server name and select Configure and Enable Routing and Remote Access.
   • In the Routing and Remote Access Server Setup Wizard, select Custom Configuration and click Next.
   • Choose the services you need (e.g., VPN access, NAT, LAN routing) and click Next.
   • Click Finish and then Start service when prompted.

3. Setting Up VPN Access:

   • In the RRAS management console, right-click on Ports and select Properties.
   • Ensure that WAN Miniport (PPTP) and WAN Miniport (SSTP) are enabled.
   • Configure the VPN settings according to your organization's requirements.

4. Configuring IP Routing:

   • In the RRAS management console, expand IPv4 or IPv6 and right-click on Static Routes.
   • Select New Static Route and enter the necessary information such as Destination, Network Mask, Gateway, and Metric.
   • Click OK to add the route.

5. Using PowerShell to Configure RRAS:

   # Install the Remote Access role
   Install-WindowsFeature -Name RemoteAccess -IncludeManagementTools
   
   # Install the Routing role service
   Install-WindowsFeature -Name Routing -IncludeManagementTools
   
   # Install the DirectAccess and VPN (RAS) role service
   Install-WindowsFeature -Name DirectAccess-VPN -IncludeManagementTools
   
   # Configure RRAS for VPN and NAT
   Install-RemoteAccess -VpnType VpnSstp -NatType Full
   
   # Start the RRAS service
   Start-Service -Name RemoteAccess
