D-Link DI-206 manual Remote Network Connections

DI-206 ISDN Remote Router

be able to use network resources as if he were connected locally. When the user dials into the DI-206, the call comes into the D-channel and after answering the phone, the DI-206:

1.Identifies the Username and Password using the authentication protocol defined in the Interface Configuration, ISDN submenu. The dial-in user is not prompted for this information, but must enter it into his dialing software before dialing.

2.Checks the Username and Password against those defined in the Dial-In User Profiles and Remote Network Profiles.

3.Assuming a matching Dial-In User Profile is found, the router may configure the IP address of the remote station (as defined in the Dial-In User Profile).

4.Configures a dial-in Interface (a virtual circuit) to handle the connection.

5.Establishes the connection on whichever B-channel (physical port) is open by mapping the dial-in interface to that port.

6.In the case where the Dial-In User does not need to supply a Username and Password (Auth Type is set to None in the Interface Configuration submenu) the remote computer must have its own IP address.

Remote Network Connections

Remote networks are defined as other networks (LANs) that have WAN connections using a router, Internet server, network modem or similar device (in this document however, we will assume the remote device is a router). In almost all cases, a Remote Network Profile needs to be set up for each network that will connect to the DI-206 via the ISDN lines. The Remote Network Profiles are necessary for the router to identify and tailor the connection to the remote network’s router. Once this is done, a connection between the two routers can be made and computers on each network can communicate with each other.

Dial-In Network Connections

A dial-in network connection is very similar to a dial-in user connection. When the remote router dials into the DI-206, the call comes into the D-channel and after answering the phone, the DI-206:

1.Identifies the Username and Password using the authentication protocol defined in the Interface Configuration, ISDN submenu.

2.Checks the Username and Password against those defined in the Dial-In User Profiles and Remote Network Profiles.

3.Assuming a matching Remote Network Profile is found, the router may configure the IP address of the remote station (as defined in the Remote Network Profile).

4.Configures the specified ISDN Interface (a virtual circuit) using the configuration parameters defined in the Interface Configuration menu and the Remote Network Profile to handle the connection.

5.Establishes the connection on whichever B-channel (physical port) is open by mapping the dial-in interface to that port.

Dial-Out Network Connections

Dial-out network connections are much different than dial-in connections.

When a packet on the LAN reaches the router, the DI-206 will:
