The router links all the workstation computers on your local area network to
the global Internet. Security functions such as IP Masquerading and Firewall
filters protect your LAN against unauthorized access from outside.
1.2.2 LAN to LAN coupling
If the business runs correctly, soon it becomes time for a subsidiary or a
branch office in the global markets. Also the branch has its own network and
would like to be always up to date.
The LAN to LAN coupling links individual LANs to form one large network,
even if this means crossing continents. Using connections via switched lines,
an intelligent line management in interaction with sophisticated filter mech-
anisms ensures small connecting costs.
Faster, more economically and more flexibly is the network coupling via Inter-
net. Here the broadband access to the Internet comes into play (via DSL or
the cable TV network). LAN to LAN couplings via the Internet take place as
Virtual Private Networks (VPN).
LANCOM DSL/I-1611 Office can be upgraded with the LANCOM VPN Option
and supports the set-up of VPNs then.
1.2.3 Homeworking with Remote Access
The work of many office workers in modern organizations is less and less
dependent on any definite location - the most important factor is unimpaired
access to shared and freely available information.
Remote Access (RAS) is the magic word here. Employees working from home
or field staff can dial into the company network via ISDN. When working with
remote access,
LANCOM Office protects the company network: the callback
function only grants access to known and registered users. And for a more
comfortable settlement of accounts, the connecting costs are centrally regis-
tered in the company.
All devices of the
LANCOM Office series support remote access services via
ISDN. Optionally, the LANCOM DSL/I-1611 Office supports VPN-based RAS
as well.
