A LAN comprises a collection of LAN clients, which are networked devices on your premises. A
LAN client can be a computer, a printer, a Voice-over-IP (VoIP) phone, a mobile phone, a
gaming console, an Internet Protocol Television (IPTV), etc, and can have either a wired
(using Ethernet cabling) or wireless (using Wi-Fi) network connection.
LAN clients within the same LAN are normally able to communicate with one another directly,
as they are peers to one another, unless measures, such as firewalls or VLANs, have been put
in place to restrict such access. Nowadays the most common LAN firewalls are implemented
on the LAN client itself. For example, Microsoft Windows since Windows XP and Apple OS X
have built-in firewalls that can be configured to restrict traffic coming in and going out of the
computer. VLANs, on the other hand, are usually set up using network switches or routers,
such as the Vigor2862.
To communicate with the hosts outside of the LAN, LAN clients have to go through a network
gateway, which in most cases is a router (such as the Vigor 2862) that sits between the LAN
and the ISP network, which is the WAN. The router acts as a director to ensure traffic
between the LAN and the WAN reach their intended destinations.

There are eight subnets provided by the router which allow users to divide groups into
different subnets (LAN1 – LAN8). In addition, different subnets can link for each other by
configuring Inter-LAN Routing. At present, LAN1 setting is fixed with NAT mode only. LAN2 –
LAN8 can be operated under NAT or Route mode. IP Routed Subnet can be operated under
Route mode.
