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.

by the deployment of VPN.
