Routing
Configure Static Route
Use this screen to view and configure static route rules on the Zyxel Device. A static route is used to save time and bandwidth usage when LAN devices within an Intranet are transferring files or packets, especially when there are more than two Internet connections in your home or office network. Click Network Setting > Routing to open the Static Route screen.
Network Setting > Routing > Static Route
The following table describes the labels in this screen.

Description
Add New Static Route
Click this to set up a new static route on the Zyxel Device.
#
This is the number of an individual static route.
Status
This field indicates whether the rule is active (yellow bulb) or not (gray bulb).
Name
This is the name of the static route.
Destination IP
This parameter specifies the IP network address of the final destination. Routing is always based on network number.
Subnet Mask/ Prefix Length
This parameter specifies the IP network subnet mask of the final destination.
Gateway
This is the IP address of the gateway. The gateway is a router or switch on the same network segment as the device's LAN or WAN port. The gateway helps forward packets to their destinations.
Interface
This is the WAN interface through which the traffic is routed.
Modify
Click the Edit icon to go to the screen where you can set up a static route on the Zyxel Device.
Click the Delete icon to remove a static route from the Zyxel Device.
Add or Edit Static Route
Use this screen to add or edit a static route. Click Add New Static Route in the Static Route screen, the following screen appears. Configure the required information for a static route.
*The Gateway IP Address must be within the range of the selected interface in Use Interface.

Description
Active
Click this switch to activate static route. Otherwise, click to disable.
Route Name
Enter a name for your static route. You can use up to 15 printable characters except [ " ], [ ` ], [ ' ], [ < ], [ > ], [ ^ ], [ $ ], [ | ], [ & ], or [ ; ]. Spaces are allowed.
IP Type
Select between IPv4 or IPv6. Compared to IPv4, IPv6 (Internet Protocol version 6), is designed to enhance IP address size and features. The increase in IPv6 address size to 128 bits (from the 32-bit IPv4 address) allows up to 3.4 x 1038 IP addresses. The Zyxel Device can use IPv4/IPv6 dual stack to connect to IPv4 and IPv6 networks, and supports IPv6 rapid deployment (6RD).
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.
Subnet Mask
If you are using IPv4 and 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. Enter the IP subnet mask here.
*This field appears only when you select IPv4 in the IP Type field.
Prefix Length
If you are using IPv6, enter the address prefix length to specify how many most significant bits in an IPv6 address compose the network address.
*This field appears only when you select IPv6 in the IP Type field.
Use Gateway IP Address
The gateway is a router or switch on the same network segment as the device's LAN or WAN port. The gateway helps forward packets to their destinations.
Click this switch to enable or disable the gateway IP address. When the switch goes to the right, the function is enabled. Otherwise, it is not.
Gateway IP Address
Enter the IP address of the gateway.
User Interface
Select the WAN interface you want to use for this static route.
OK
Click this to save your changes.

An Example of Adding a Static Route
In order to extend your Intranet and control traffic flowing directions, you may connect a router to the Zyxel Device’s LAN. The router may be used to separate two department networks. This tutorial shows how to configure a static routing rule for two network routings.
In the following figure, router R is connected to the Zyxel Device’s LAN. R connects to two networks, N1 (192.168.1.x/24) and N2 (192.168.10.x/24). If you want to send traffic from computer A (in N1 network) to computer B (in N2 network), the traffic is sent to the Zyxel Device’s WAN default gateway by default. In this case, B will never receive the traffic.
You need to specify a static routing rule on the Zyxel Device to specify R as the router in charge of forwarding traffic to N2. In this case, the Zyxel Device routes traffic from A to R and then R routes the traffic to B.
This tutorial uses the following example IP settings:

R’s N2
192.168.10.2
B
192.168.10.33
To configure a static route to route traffic from N1 to N2:
1 Log into the Zyxel Device’s Web Configurator.
2 Click Network Setting > Routing.
3 Click Add new Static Route in the Static Route screen.
4 Configure the Static Route Setup screen using the following settings:
Click the Active button to enable this static route. When the switch goes to the right, the function is enabled. Enter the Route Name as R.
Set IP Type to IPv4.
Enter the Destination IP Address 192.168.10.1 and IP Subnet Mask 255.255.255.0 for the destination, N2.
Click the Use Gateway IP Address button to enable this function. When the switch goes to the right, the function is enabled. Enter 192.168.1.253 (R’s N1 address) in the Gateway IP Address field.
Select Default as the Use Interface.
Click OK.
Now B should be able to receive traffic from A. You may need to additionally configure B’s firewall settings to allow specific traffic to pass through.
