VLAN
A Virtual Local Area Network (VLAN) is a network of computers that behave as if they are
connected to the same wire even though they may be physically located on different seg-
ments of a LAN. You set up VLANs by configuring the Gateway software rather than hard-
ware. This makes VLANs very flexible. An important advantage of VLANs is that when a
computer is physically moved to another location, it can stay on the same VLAN without
hardware reconfiguration. VLANs behave like separate and independent networks.
When you click the
VLAN
link the
VLANs
page appears. If no VLANs are configured, the
VLANs page displays no entries.

An example of multiple VLANs is shown below:
To create a VLAN, click the
Ad
d
button.
The
VLAN Entry
page appears.
You can create up to 32 VLANs, and you can also restrict any VLAN, and the computers on
it, from administering the Gateway.

The
VLAN Port Configuration
screen appears.
•
Port interfaces available for this VLAN are listed in the left hand screen.
Displayed port interfaces vary depending on the kinds of physical ports on your Gate-
way, for example, Ethernet, USB, and/or wireless.
Also, if you have multiple wireless SSIDs defined, these may be displayed as well (See
Enable Multiple Wireless IDs
on
page

)

Configure
For Netopia VGx technology models, separate Ethernet switch ports are displayed and
may be configured.
To enable any of them on this VLAN, select one, and click the
Ad
d
button.
Typically you will choose a physical port, such as an Ethernet port (example:
ethernet1
)
or a wireless SSID (example:
ssid1
), and make the port routable by specifying
lan-
uplink
.

When you are finished, click the Alert icon in the upper right-hand corner of the screen,

☛
Note:
To make a set of VLANs non-routable, the
lan-uplink
port must be included in
at least one VLAN. It must then be excluded from any VLANs that are non-
routable.
