LANCOM Wireless DSL – LANCOM Wireless ADSL

 Chapter 5: Linking two networks

 In case your device has an ISDN connection, the wizard asks whether the

remote site has ISDN as well.

 The type of IP address must be stated for both sides for VPN connections

via the Internet. There are two types of IP addresses: static and dynamic.

An explanation of the two IP address types can be found in the reference

manual.

Thanks to Dynamic VPN, connections can be enabled not only

between gateways with fixed, static IP addresses, but even between gate-

ways with dynamic IP addresses. The active initiation of VPN connec-

tions towards remote sites with dynamic IP addresses requires ISDN.

 If you haven't already named your LANCOM Wireless DSL, the wizard will

ask you for a new, unique device name. With this entry, you will rename

your LANCOM Wireless DSL. Be sure to give the two devices different

names.

 The name of the remote station is needed for its identification.

 Enter the subscriber number of the remote station in the ISDN subscriber

number field. The complete subscriber number including all necessary

area and country codes is required.

 The stated ISDN caller ID is used to identify and authenticate callers.

When a LANCOM Wireless DSL receives a call, it compares the ISDN caller

ID entered for the remote station with the actual caller ID transferred via

VPN IP address of remote station '10.0.2.100' '10.0.1.100'
