Click Start/Programs/Administrative Tools 2. Click Routing and Remote Access 3. In the console tree, select the server on which you want to activate RRAS 4. Click Action/Configure and Enable Routing and Remote Access to open the RRAS setup wizard 5. Click Next to open the Common Configurations screen 6. Click Manually Configured Server to enable the server with default settings 7. Click Next, then Finish 8. When asked Do you want to start the RRAS?, click Yes. 6
Configuring RRAS When RRAS is manually enabled, the default settings apply. You can configure RRAS according to your requirements at a later date. To configure RRAS, you use the Properties dialog box (Right-click server, click Properties) 7 Configuring RRAS Note: Tabs depend on protocols installed on your server 8 General Security IP PPP Event Logging Configuring RRAS Used to specify whether server will be configured as a router for LAN only, as a router for a LAN and demand-dial routing, as a RAS, or both a router and a RAS Used to choose one of two types of authentication providers to validate remote access clients Used to specify settings for the IP protocols (e.g. method for distributing IP addresses to remote clients. Used to configure Point-to-Point Protocol to specify whether a remote client can establish multilink connections Used to manage and monitor a RRAS server by selecting the type of event to record. 9
Configuring RRAS 2. Right-click RRAS server and click Properties 3. Notice the default selections in the General tab. 4. Click the IP tab. Make sure that the Enable IP routing and the Allow IP-based remote access and demand-dial connections check boxes are selected. Note: if you allow IP routing, dialup clients can access the entire LAN. If you only want to allow dial-up clients to access resources on the RRAS server, clear this check box. 5. Click the Security tab. Windows Authentication is the default provider and Windows accounting is the accounting provider by default. 6. Click the Event Logging tab. You should select the Log the maximum amount of information option button and the Enable Point-to-Point (PPP) logging check box if you want to troubleshoot connection problems. 7. Click OK to close the Properties dialog box. 10 Monitoring RRAS In the server Status node in the Routing and Remote Access console, you can verify: the state of the server (started, Stopped, Paused) The type of server The number of ports in use The Up time (length of time server has been running since RRAS server was last started). The log files that contains the monitoring data are stored by default in the 11 Monitoring RRAS 2. Double-click the RRAS server to expand the node. Select Remote Access Logging. 3. Right-click Local File in the Details pane and click Properties 4.

Note: Can use the Net Shell (Netsh) command-line utility to manage and troubleshoot RRAS. 12
Creating a Remote Access Policy Remote Access Policies are used to: Control what connections attempts will be rejected Determine which users can access the network and to prevent unauthorized access. Determine connection time, etc. Three components in Remote Access Policy: Conditions, Permissions, and Profile. Remote Access Policies are usually stored locally on the RRAS server. They are not stored in Active Directory. 13 Creating a Remote Access Policy 2. Double-click the RRAS server to expand the node, if necessary, and select the Remote Access policies node. Notice that there is a default policy named Allow access if dial-in permission is enabled. 3. Click Action/New Remote Access Policy to open the Add Remote Access Policy wizard. 4. Type Srvdcxx Remote Access Policy in the Policy Friendly name text box. 5. Click Next to open the Conditions screen. Click Add to open the Select Attribute dialog box. 6. Select Day-and-Time restrictions in the name column and click Add to open the Time of day constraints dialog box. 7. Restrict access to the RRAS to M-F from 9AM to 6PM. 14 Creating a Remote Access Policy (cont.) 8. Click OK 9. Click Add to reopen the Select Attribute dialog box.
