1 Introduction
The models of the LANCOM router series operate as powerful Dynamic VPN
gateways with 200, 500 or 1000 VPN channels for remote sites or mobile
users.
Due to the Fast Ethernet uplink, the devices are the ideal partner for almost
all WAN connection variants. The integrated multi protocol router and the
integrated firewall enable a secure internet access for the local network. The
ISDN interface is mainly used to establish Dynamic VPN connections to remote
sites with dynamic IP addresses.
1.1 Which use does VPN offer?
A VPN (Virtual Private Network) can be used to set up cost-effective, public
IP networks, for example via the ultimate network: the Internet.
The model LANCOM 7111 VPN is equipped with 100 VPN channels by
default, the LANCOM 8011 VPN with 200 channels. With the addi-
tional LANCOM VPN Option the LANCOM 8011 VPN can be upgraded
to 500 or 1000 channels.
While this may sound unspectacular at first, in practice it has profound effects.
To illustrate this, let's first look at a typical corporate network without VPN
technology. In the second step, we will see how this network can be optimized
by the deployment of VPN.
