SUMMARY
This article discusses information on how to configure a Routing and Remote
Access Service (RRAS) LAN-to-LAN Routing Dial-on-Demand (DOD) connection
over Nwlink.
MORE INFORMATION
To configure a RRAS LAN-to-LAN Routing DOD connection over Nwlink, start
the RRAS Administration utility, and then perform the following steps:
- Right-click the LAN and Demand Dial Interfaces key, and click Add
   Interface.
 
 - The name to be typed MUST be the name of a valid user account
      on the Dial-up RRAS server, and then click Next.
 
 
- Select "Route IPX packets on this interface" only, and then click
      Next.
 
 
- Type the telephone number of the Dial-up server, and then click
      Next.
 
 
- Type the user name, domain, and password of a valid user account
      on the Dial-up server, and then click Finish.
 
 
- Select Enable IPX on this Interface and make sure that both
      locations are set to use the same Dial In Control Protocol, then
      click OK.
 
 
- Make sure that Accept Broadcasts are enabled. If Always is selected,
      a Demand-Dial connection will be established whenever a Windows NT-
      based router receives a NetBIOS over IPX broadcast. If Statically
      Seeded is selected, only broadcast packets that are defined for a
      statically configured NetBIOS name, configured under the Static
      NetBIOS Names key, will be propagated. If only When Interface is Up
      is Selected it will act as if it was configured for Always, but only
      when the DOD connection is active. Click OK.
 
 
- Make sure that the Update Mode for RIP for IPX is set to Auto-
      Static, then click OK.
 
 
- Make sure that the Update Mode for SAP for IPX is set to Auto-
      Static, then click OK.
 
 
 
- Select the NetBIOS Broadcasts key, and make sure that both the Internal
   and External network interface cards (NICs) are configured to Accept and
   Deliver NetBIOS Broadcasts. If either NIC is not configured to Accept
   and Deliver NetBIOS broadcasts, then right-click the NetBIOS Boradcasts
   key, and then click Configure Interface.
- Each interface should be set to Accept Broadcasts and Deliver Broadcasts
   and be set to Always for full LAN-to-LAN connectivity.
- Select the RIP for IPX key, and make sure that both the Internal and
   External NICs are configured to perform in a Standard update mode. If
   either NIC is not configured in this manner, right-click the RIP for IPX
   key, and then click Configure Interface.
- Configure each interface to perform in a Standard update mode.
- Select the SAP for IPX key and make sure that both the Internal and
   External NICs are configured to perform in a Standard update mode If
   either NIC is not configured in this manner, right-click the SAP for IPX
   key, and then click Configure Interface.
- Make sure that the Update Mode for both the Internal and External NIC
   is set to Standard.
- Right-click the Static NetBIOS Names key if you are using a Statically
   Seeded delivery method for NetBIOS Resolution, and click Add NetBIOS
   Name.
- Type the NetBIOS name of the remote computer that you wish to connect
   to. Leave the Type field blank so it will propagate all computer types
   associated with the name. Click the DOD connection that will be used to
   communicate with the other RRAS router.
- After the steps above have been performed on both RRAS servers, select
    the IPX Routing Summary key, and click the DOD connection that will be
    used to communicate with the other RRAS router. Right-click the IPX
    Routing Summary key, and then click Connect.
- After you've connected, select IPX Routing Summary key, and then the
    DOD connection that will be used to communicate with the other
    Steelhead router.
- Right-click the IPX Routing Summary key, and then click Update
    Routes.
At this point, Nwlink LAN-to-LAN routing should be successfully installed,
and full network connectivity is available.
