Static Route Setup Screen
To edit a static route, click the edit icon under
Modify
. The following screen displays. Fill in
the required information for each static route.
Table 59
Management > Static Route > IP Static Route
LABEL
DESCRIPTION
#
This is the index number of an individual static route. The first entry is for the
default route and not editable.
Name
This is the name that describes or identifies this route.
Active
This icon is turned on when this static route is active.
Click the
Edit
icon under
Modify
and select the
Active
checkbox in the
Static
Route Setup
screen to enable the static route. Clear the checkbox to disable this
static route without having to delete the entry.
Destination
This parameter specifies the IP network address of the final destination. Routing
is always based on network number.
Gateway
This is the IP address of the gateway. The gateway is an immediate neighbor of
your NBG334W that will forward the packet to the destination. On the LAN, the
gateway must be a router on the same segment as your NBG334W; over the
WAN, the gateway must be the IP address of one of the remote nodes.
Modify
Click the
Edit
icon to open the static route setup screen. Modify a static route or
create a new static route in the
Static Route Setup
screen.
Click the
Remove
icon to delete a static route.

Table 60

LABEL
DESCRIPTION
Route Name
Enter the name of the IP static route. Leave this field blank to delete this static
route.
Active
This field allows you to activate/deactivate this static route.
Private
This parameter determines if the NBG334W will include this route to a remote
node in its RIP broadcasts.
Select this check box to keep this route private and not included in RIP
broadcasts. Clear this checkbox to propagate this route to other hosts through RIP
broadcasts.
Destination IP
Address
This parameter specifies the IP network address of the final destination. Routing is
always based on network number. If you need to specify a route to a single host,
use a subnet mask of 255.255.255.255 in the subnet mask field to force the
network number to be identical to the host ID.
IP Subnet Mask
Enter the IP subnet mask here.
Gateway IP
Address
Enter the IP address of the gateway. The gateway is an immediate neighbor of
your NBG334W that will forward the packet to the destination. On the LAN, the
gateway must be a router on the same segment as your NBG334W; over the
WAN, the gateway must be the IP address of one of the Remote Nodes.
Metric
Metric represents the “cost” of transmission for routing purposes. IP routing uses
hop count as the measurement of cost, with a minimum of 1 for directly connected
networks. Enter a number that approximates the cost for this link. The number
need not be precise, but it must be between 1 and 15. In practice, 2 or 3 is usually
a good number.

Bandwidth Management
This chapter contains information about configuring bandwidth management, editing rules and
viewing the NBG334W’s bandwidth management logs.
16.1
Bandwidth Management Overview
ZyXEL’s Bandwidth Management allows you to specify bandwidth management rules based
on an application and/or subnet. You can allocate specific amounts of bandwidth capacity
(bandwidth budgets) to different bandwidth rules.
The NBG334W applies bandwidth management to traffic that it forwards out through an
interface. The NBG334W does not control the bandwidth of traffic that comes into an
interface.
Bandwidth management applies to all traffic flowing out of the router, regardless of the
traffic's source.
Traffic redirect or IP alias may cause LAN-to-LAN traffic to pass through the NBG334W and
be managed by bandwidth management.
The sum of the bandwidth allotments that apply to the WAN interface (LAN to WAN,
WLAN to WAN, WAN to WAN / NBG334W) must be less than or equal to the
Upstream
Bandwidth
that you configure in the
Bandwidth Management
Advanced
screen.
The sum of the bandwidth allotments that apply to the LAN port (WAN to LAN, WLAN
to LAN, LAN to LAN / NBG334W) must be less than or equal to 100,000 kbps (you
cannot configure the bandwidth budget for the LAN port).
The sum of the bandwidth allotments that apply to the WLAN port (LAN to WLAN,
WAN to WLAN, WLAN to WLAN / NBG334W) must be less than or equal to 54,000
kbps (you cannot configure the bandwidth budget for the WLAN port).
16.2
Application-based Bandwidth Management
You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, E-
mail and Video for example).
16.3
Subnet-based Bandwidth Management
You can create bandwidth classes based on subnets.

The following figure shows LAN subnets. You could configure one bandwidth class for subnet
A
and another for subnet
B
.

Subnet-based Bandwidth Management Example
16.4
Application and Subnet-based Bandwidth Management
You could also create bandwidth classes based on a combination of a subnet and an
application. The following example table shows bandwidth allocations for application specific
traffic from separate LAN subnets.
16.5
Bandwidth Management Priorities
The following table describes the priorities that you can apply to traffic that the NBG334W
forwards out through an interface.

Bandwidth Management Priorities
PRIORITY LEVELS: TRAFFIC WITH A HIGHER PRIORITY GETS THROUGH FASTER WHILE
TRAFFIC WITH A LOWER PRIORITY IS DROPPED IF THE NETWORK IS CONGESTED.
High
Typically used for voice traffic or video that is especially sensitive to jitter (jitter
is the variations in delay).
