SYMPTOMS
When you add a network interface to a remote access server in the Routing and Remote Access utility, a default route for that interface may not appear in the routing table.



CAUSE
This issue may occur if both of the following conditions are true:
 * You remove a network interface from the remote access server.

-and-
 * You re-add that network interface to the remote access server.



WORKAROUND
To work around this issue, use one of the following methods.

Method 1: Manually Add the Default Route for the Interface
Use the Route Add command to manually add the default route for the network interface that you added. To do so:  Click Start, click Run, type cmd in the Open box, and then click OK. Type route print, and then press ENTER to view the routing table. Note the interface number of the network interface that you re-added. Type the following command, and then press ENTER

route add 0.0.0.0 mask 0.0.0.0  metric   if

where  is the IP address of the default gateway for this interface, and where   is the number that corresponds to the network interface that you added (for example, 2 ). For example, if your default gateway IP address is 192.168.1.1 and the interface number is 2, type the following command, and then press ENTER:

route add 0.0.0.0 mask 0.0.0.0  metric   if

 Type route print to verify that the new default route appears in the routing table. Close the command prompt.

Method 2: Restart the Remote Access Service
Restart the remote access service. The default route for the re-added network interface is added to the Windows routing table. To do so:
 * 1) Start the Routing and Remote Access utility.
 * 2) Under Routing and Remote Access, right-click the server where you re-added the network interface, point to All Tasks, and then click Restart.

Method 3: Restart the Server
Restart the remote access server. The default route for the re-added network interface is added to the Windows routing table.
