Static Routing

9.1 Overview

The ZyXEL Device usually uses the default gateway to route outbound traffic from computers on the LAN to the Internet. To have the ZyXEL Device send data to devices not reachable through the default gateway, use static routes.

For example, the next figure shows a computer (A) connected to the ZyXEL

Device’s LAN interface. The ZyXEL Device routes most traffic from A to the

Internet through the ZyXEL Device’s default gateway (R1). You create one static route to connect to services offered by your ISP behind router R2. You create another static route to communicate with a separate network behind a router R3 connected to the LAN.

Entry

DESCRIPTION

Click this to configure a new static route.

#

Status

This is the index number of the entry.

This field displays whether the static route is active or not. A yellow bulb signifies that this route is active. A gray bulb signifies that this route is not active.

Name This is the name that describes or identifies this route.

Destination IP This parameter specifies the IP network address of the final destination.

Routing is always based on network number.

Subnet Mask 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.

Modify Click the Edit icon to edit the static route on the ZyXEL Device.

Click the Delete icon to remove a static route from the ZyXEL Device. A window displays asking you to confirm that you want to delete the route.

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.

Enter the IP subnet mask here.
