Event ID 20179 — RRAS Routing Interfaces
Applies To: Windows Server 2008 R2
The server running Routing and Remote Access uses a routing interface to forward unicast IP and multicast IP packets. There are two types of routing interfaces: LAN interfaces and demand-dial interfaces. A LAN interface is a physical interface that typically represents a local area connection that uses local area networking technology such as Ethernet or token ring. A demand-dial interface is a logical interface that represents a point-to-point connection. The point-to-point connection is based on either a physical connection, such as two routers connected over an analog phone line that uses modems, or a logical connection, such as two routers connected over a virtual private network (VPN) connection that uses the Internet.

|Message:||Interface: %1 is unreachable because there are no modems (or other connecting devices) available for use by this interface.|
Check the availability and response of the modem or other connection device
Possible resolutions include:
- If the modem was disconnected or turned off, reconnect or turn on your modem, and then either restart the operating system or use Device Manager to scan for new hardware.
- If the communications port is already in use by another connection, end the connection or change the connection to use a different port.
To verify that the remote access server can accept connections, establish a remote access connection from a client computer.
To create a VPN connection:
- Click Start, and then click Control Panel.
- Click Network and Internet, click Network and Sharing Center, and then click Set up a connection or network.
- Click Connect to a workplace, and then click Next.
- Complete the steps in the Connect to a Workplace wizard.
To connect to a remote access server:
- In Network and Sharing Center, click Manage network connections.
- Double-click the VPN connection, and then click Connect.
- Verify that the connection was established successfully.
