Introduction to the Routing and Remote Access Service

سال 1996 شرکت Microsoft برنامه یا سرویس RAS در WIN NT 3.51 Service Pack 2 را گسترش داد و در واقع یک سرویس بنام RRAS را جایگزین آن کرد .و آن را در WIN NT 4 کامل کرد .

مواردی که در زیر مشاهده می کنید مواردی می باشد که به این Component اضافه شد .در این سرویس MultiProtocol Routing و Remote Access هر دو در یک جا کنترل می شود .

 

MultiProtocol Routing (Routing Information Protocol (RIP) for IP, RIP for IPX, and the Service Advertising (SAP) for IPX).

 

RRAS for Windows NT 4.0 added support for:

  1. RIP version 2 routing protocol for IP.

  2. Open Shortest Path First (OSPF) routing protocol for IP.

  3. Demand-dial routing, the routing over on-demand or persistent WAN links such as analog phone, ISDN, or using the Point-to-Point Tunneling Protocol (PPTP).

  4. ICMP Router Discovery.

  5. Remote Authentication Dial-In User Service (RADIUS) client.

  6. IP and IPX packet filtering.

  7. Point-to-Point Tunneling Protocol (PPTP) support for router-to-router VPN connections.

  8. A graphical user interface administrative program called Routing and RAS Admin and a command-line utility called Routemon.

Windows 2000 Routing and Remote Access Service

اما در WINDOWS 2000 Server نیز Microsoft این سرویس را گسترش داد و مواردی که در زیر مشاهده می کنید به آن اضافه کرد .

  • Internet Group Management Protocol (IGMP) and support for multicast boundaries.

  • Network address translation (NAT) with addressing and name resolution components that simplify the connection of a small office/home office (SOHO) network to the Internet.

  • Integrated AppleTalk routing.

  • Layer Two Tunneling Protocol (L2TP) over IP Security (IPSec) support for router-to-router VPN connections.

  • Improved administration and management tools. The graphical user interface program is the Routing and Remote Access administrative utility, a Microsoft Management Console (MMC) snap-in. The command-line utility is Netsh.

All of the combined features of the Windows 2000 Routing and Remote Access service make a Windows 2000 Server–based computer function as the following:

  • Multiprotocol router

    A Routing and Remote Access service computer can route IP, IPX, and AppleTalk simultaneously. All routable protocols and routing protocols are configured from the same administrative utility.

     

  • Demand-dial router

    A Routing and Remote Access service computer can route IP and IPX over on-demand or persistent WAN links, such as analog phone lines or ISDN, or over VPN connections using either PPTP or L2TP over IPSec.

     

  • Remote access server

    A Routing and Remote Access service computer can act as a remote access server providing remote access connectivity to dial-up or VPN remote access clients using IP, IPX, AppleTalk, or NetBEUI.

 
. .
Authentication and Authorization

شناسایی یک User توسط RRAS در دو مرحله انجام می شود  .

Authentication

زمانی را که RAS Client برای RAS Serv یک Account را با یک Password بصورت Clear text و یا Encryption ارسال می کند را Authentication گفته می شود .

در این میان این ارتباط بین دو End System را Authentication Protocol محافظت می کنند .

Authorization

در این مرحله باید کلیه اطلاعات RAS Client توسط سرور چک شود تا اجازه ایجاد یک Connection داده شود .

RADIUS Server

کلیه RAS Server ها می توانند Client یک یا چند RADIUS Serv باشند در این حالت کلیه  عملیاتهای Authentication و Authorization توسط RADIUS انجام می شود و به

RAS Server ها اطلاع داده می شود .

 
. .
Accounting

RRAS می تواند یک Log file برای Account های سرور ها ایجاد کند .دو حالت دارد اول اینکه  بصورت Locally بر روی سرور ها باشد دوم اینکه

بر روی RADIUS Server این Log وجود داشته باشد .

 
. .
Installation and Configuration

شما می توانید این سرویس را در Administration Tools خود بنام Routing and Remote Access Service پیدا کنید زمانی که این MMC  باز کردید .

سپس برای راه اندازی سرور باید بر روی آن Right-click کرد سپس گزینه Configure and enable routing and remote access را نتخاب کرد سپس Wizard مورد نظر را انتخاب کرد .

 

To enable and configure the Routing and Remote Access service

  1. Run Routing and Remote Access from the Administrative Tools folder.

  2. For the local computer, right-click the server icon and select Configure and Enable Routing and Remote Access.

    For a remote computer, right-click the Server Status icon and click Add Server. In the Add Server dialog boxes, select the server you want to add.

  3. To configure your remote access router, in the Routing and Remote Access Server Setup Wizard, select the appropriate options.

Once the wizard has finished, the remote access router is enabled and configured based on your selections in the wizard. To do further configuration, use the Routing and Remote Access snap-in.

 
. .
Refreshing the Configuration

شما نمی توانید این سرویس را از طریق Add/Remove Program پاک کنید بلکه می توانید این سرویس را Disable و یا Stop کنید .

To refresh the configuration of the Routing and Remote Access service

  1. Run Routing and Remote Access from the Administrative Tools folder.

  2. For the appropriate computer, right-click the server icon and select Disable Routing and Remote Access.

  3. When prompted with the warning dialog box, select Yes.

  4. To configure the Routing and Remote Access service configuration, use the enable and configure procedure.

If you disable the Routing and Remote Access service, all current configuration for the service, including routing protocol configuration and demand-dial interfaces, is removed and all currently connected clients are disconnected.
