RAS Application using Remote User Database
The initial software loading process would be the same as for the RAS application using Radius,
except that now instead of setting up Radius parameters, you will assemble a Remote User
Database. A typical RAS application using the Remote User Database is shown in Figure 4-2.
Figure 4-2. RAS Application using Remote User Data Base
During the software loading process when the Default Parameters dialog box displays, both IPX and
IP protocols are enabled and a default Ethernet IP address and (subnet) mask are displayed in the IP
LAN group. For this RAS application, you would disable the IPX protocol and then change the default
LAN IP address and mask to the unique IP addressing scheme for your network. The address
assigned to your RASFinder's Ethernet port can be any address that is recognizable by your
network's backbone.
In this typical RAS application, the IP network address is 192.168.2.xxx. For the purpose of this
discussion, we are assigning the IP address 192.168.2.10 to the Ethernet port on the RASFinder.
After this address is entered into the IP Address field of the Default Parameters dialog box, the next
three sequential IP addresses (192.168.2.11, 192.168.2.12, and 192.168.2.13) are assigned to the
WAN ports. These three IP addresses, in the same network (with the Ethernet LAN), are associated
with the respective WAN ports so that when the remote users dial into the WAN ports, they always
appear (to the rest of the IP network) at these respective addresses.
Before remote users can dial into the network, a user profile has to be set up in the proprietary
remote user database using the Remote User Data base utility. This data base utility is provided with
the RASFinder software. The RASFinder network administrator builds this database by adding
