The first entry in Figure 3-42indicates: If there are packets being sent to a device with IP address of

172.31.70.28and subnet mask of 255.255.255.0, the Router will forward the packets from WAN1 port to the next hop of 116.10.1.254.

Application Example

There is a network topology as the following figure shown:

If the LAN port of TL-ER6120with Non-NAT or Classic system modeis connected to LAN1 with subnet of 192.168.0.0/24, while the LAN port of another Router R1 is connected to LAN2 with network of 192.168.2.0/24. Meanwhile, the WAN ports of the two routers are interconnected and within the same network. Now a host under TL-ER6120 and within network of LAN1 desires to communicate with the host within network of LAN2.

You can set a Static Route entry: Enter the WAN IP address of R1 (116.31.88.16) in the Next Hop field on the Static Route page of TL-ER6120 as the following figure shown, then click the <Add> button to save the entry.
