Static routes
For almost all Internet traffic, routes are automatically and dynamically selected. You
can also set up a fixed, static route. Typically, you only need to add static routes when
you have more than one router or multiple IP subnets on your network.
As an example of when a static route is needed, consider the following case:
•
Your main Internet access is through a cable modem to your ISP. The cable modem
is connected to your Orbi Pro WiFi 6 router.
•
Your business network also includes an ADSL router that you use to access a remote
office site. This ADSL router is connected to a DSL modem, which is used on-demand
only.
•
Your LAN subnet is 192.168.1.0, and the ADSL router’s address on your LAN is
192.168.1.100.
•
The public IP address range at the remote office site is 134.177.0.0.
When you set up your Orbi Pro WiFi 6 router, two implicit static routes were created:
1. A default route was created between your Orbi Pro WiFi 6 router and the cable
modem that connects to your ISP.
2. A second static route was created between your Orbi Pro WiFi 6 router and your
LAN for all 192.168.1.0 addresses.
With this configuration, if you try to access a device on the 134.177.0.0 network at the
remote office site, your Orbi Pro WiFi 6 router forwards your request to your ISP. In turn,
the ISP forwards your request to the remote office site, where the firewall will deny the
request.
In this situation, you must define a static route, telling your Orbi Pro WiFi 6 router to
access 134.177.0.0 addresses through your ADSL router at its LAN address of
192.168.1.100.
Here is an example static route setting for this configuration:
•
Destination IP address and subnet mask settings: The route applies to all addresses
at the remote site, so set the destination IP address to 134.177.0.0 and the subnet
mask to 255.255.255.0.
•
Gateway IP address: Traffic for addresses in the 134.177.0.0 network must be
forwarded to the ADSL router, so set the gateway IP address to 192.168.1.100 (the
ADSL router’s address on your LAN).
•
Private route: Make the static route private as a security precaution in case Routing
Information Protocol (RIP) is activated. A private route is not reported in RIP messages.
