DI-1162 Remote Access Router
Configuration and Management 49
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-1162 via a
WAN connection. 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-1162, the call
comes into the WAN port and after answering the phone, the DI-1162:
1. Identifies the Username and Password using the authentication
protocol defined in the
Interface Configuration
,
WAN
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
WAN 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.
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-1162 will:
1. Check its routing table to try to identify where this packet should
go. It looks for two variables in the routing table,
Gateway address
and
Interface
. There are four possible results:
