Choose Single-User Dial-in when your dial-in user will access a server LAN Modem
via a single ISDN terminal adapter, or via a LAN Modem that will share one IP
address for all attached workstations. Note that in this scenario, workstations on
the server-side cannot access client-side resources.
LAN Modem Site-to-Site Dial-in
LAN Modem Site-to-Site dial-in describes a scenario where a LAN Modem dials
into another LAN Modem, with multiple IP addresses assigned to each LAN device
on both sides of the connection, as shown in Figure 7. This scenario allows
workstations on both sides of the connection to access servers and resources on
each LAN, providing bidirectional LAN-to-LAN connectivity.
When the LAN Modem Site-to-Site scenario is first configured via the Dial-in
Wizard, the client LAN Modem (or the LAN Modem which has not been
designated Site A) will automatically change its default IP address and restart. This
is to distinguish between each LAN Modem's subnet address, which by default are
identical (192.168.1.x).

Figure 7 LAN Modem Site to Site Dial-in
In LAN Modem Site-to-Site Dial-in, the target LAN Modem provides its WAN IP
address as the DNS server to the client LAN Modem. This scenario allows users
across the connection direct access to all available workstations via domain name
or IP address.
Choose LAN Modem Site-to-Site when your dial-in user will access a LAN Modem
from another LAN Modem, where LAN resources are accessible on both ends of
the connection.
Advanced Dial-in
Use Advanced Dial-in for scenarios where a router other than a LAN Modem dials
into a LAN Modem. Advanced Dial-in assumes that both routers have been
manually configured for static IP addressing, and each employs a unique range of
addresses.
Choose Advanced Dial-in if your LAN is using static IP addressing, or your dial-in
user will be accessing the LAN Modem from a router other than a LAN Modem.
Note that Advanced Dial-in is the most complex dial-in scenario and may require
the assistance of your MIS administrator. Refer to "Configuring Dial-in User
Parameters" for more information.
