How to set up Static Routing on the Linksys Gigabit VPN Routers, LRT214 and LRT224

When there are more than one (1) router and IP subnets, the routing mode for the device should be configured as Static Routing.  Static Routing enables different network nodes to seek necessary paths automatically.  It also enables different network nodes to access each other.

NOTE:  The Linksys Gigabit VPN Routers, LRT214 and LRT224 do NOT need static routes configured for the IP subnets that are directly attached to its WAN or LAN side.  These subnets include the multiple subnets/VLANs that are created on LRTxxx devices.

Follow the instructions below on how to configure Static Routing on the Gigabit VPN Routers, LRT214 and LRT224.   
 
Step 1:
Access the router's web-based setup page.  To learn how, click here.

Step 2:
Click the Configuration tab on the header.


Step 3:
Click Setup > Advanced Routing in the navigation tree on the left side.


 
Step 4:
Under STATIC ROUTING, enter the correct values according to the network information of your network devices:


 
  • Destination IP
Enter the remote network IP address that is to be routed.  (Example: Enter “192.168.1.0”)
  • Subnet Mask
Enter the Subnet Mask of the remote network.  (Example: Enter “255.255.255.0”)
  • Default Gateway
Enter the WAN IP Address of the remote network.

NOTE:  It is highly recommended to set Static IP on the WAN side of the routers for easy access.
  • Hop Count (Metric, max. is 15)
This is the router layer count for the IP.  If there are two (2) routers under the device, users should enter “2” for the router layer; the default is “1”.  (Max. is 15.)
  • Interface
This is to select “WAN port” or “LAN port” for network connection location.  Select LAN if this router gets Internet connectivity from a gateway router on your LAN.

Step 5:
Click Add to list.

QUICK TIP:  You can also Delete or Update the selected routing rule from the list.


Step 6:
Click  at the bottom of the page to finish the configuration.

Now that you have set up Static Routing, you may ping the IP Addresses of the computers in the remote network to test if the Static Route is working.

TIP:  Static routing is typically done when there is a subnet that is serviced by a separate router device that connects to the LAN side of LRT.  The following diagram shows where routerABC is the separate router connected to a LAN port of LRT and it is routing between the 192.168.10.0/24 and 192.168.1.0/24 subnets:
 
[WAN] LRT [LAN: 192.168.1.1/24] --- [WAN: 192.168.1.2] routerABC [LAN: 192.168.10.0/24]
                     [LAN: 192.168.2.1/24]
                     [LAN: 192.168.3.1/24]
 
In the above scenario, you need to add a static route on LRT allowing it to reach 192.168.10.0/24 by using the 192.168.1.2 as the gateway.
 
NOTE:  If the routerABC is on Router mode, you will need to add static routes to tell routerABC that,
  • to reach 192.168.2.0/24, use 192.168.1.1 as the gateway
  • to reach 192.168.3.0/24, use 192.168.1.1 as the gateway
