9.4 VLAN

A VLAN (Virtual LAN) is a logical local area network (LAN) that extends beyond a single traditional LAN to a
group of LAN segments, given specific configurations. Both WAN and LAN support 2 VLANs.

9.5 VPN

A virtual private network (VPN) extends a private network across a public network, such as the Internet. It enables
a computer to send and receive data across shared or public networks as if it were directly connected to the
private network, while benefitting from the functionality, security and management policies of the private network.
This is done by establishing a virtual point-to-point connection through the use of dedicated connections,
encryption, or a combination of the two. Currently, only PPTP is supported.
