Static Route
14.1
Overview
This chapter shows you how to configure static routes for your NBG4604.
Each remote node specifies only the network to which the gateway is directly
connected, and the NBG4604 has no knowledge of the networks beyond. For
instance, the NBG4604 knows about network N2 in the following figure through
remote node Router 1. However, the NBG4604 is unable to route a packet to
network N3 because it doesn't know that there is a route through the same
remote node Router 1 (via gateway Router 2). The static routes are for you to tell
the NBG4604 about the networks beyond the remote nodes.

What You Can Do
Use the
IP Static Route
screen (
Section 14.3 on page 142
) to view existing
static route rules.
Use the
Static Route Setup
screen (
Section 14.3.1 on page 143
) to add or edit
a static route rule.

The following table describes the labels in this screen.
Table 56
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 NBG4604 that will forward the packet to the
destination. On the LAN, the gateway must be a router on the same
segment as your NBG4604; 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.

To edit a static route, click the edit icon under

displays. Fill in the required information for each static route.

The following table describes the labels in this screen.

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.
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 NBG4604 that will forward the packet to the
destination. On the LAN, the gateway must be a router on the same
segment as your NBG4604; 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
15.1
Overview
This chapter contains information about configuring bandwidth management and
editing rules.
ZyXEL’s Bandwidth Management allows you to specify bandwidth management
rules based on an application.
In the figure below, uplink traffic goes from the LAN device (
A
) to the WAN device
(
B
). Bandwidth management is applied before sending the packets out to the
WAN. Downlink traffic comes back from the WAN device (
B
)
to the LAN device
(
A
). Bandwidth management is applied before sending the traffic out to LAN.
Figure 86
Bandwidth Management
You can allocate specific amounts of bandwidth capacity (bandwidth budgets) to
individual applications (like Web, FTP, and E-mail for example).
15.2
What You Can Do
Use the
General
screen (
Section 15.4 on page 146
) to enable bandwidth
management and assign uplink/downlink limits.
Use the
Advanced
screen (
Section 15.5 on page 147
) to configure bandwidth
management rules for the pre-defined services and applications.
