In this scenario, we will configure a LAN to LAN static route using Draytek routers that link with a point to point wireless bridge. The LANs (LAN1, LAN2, and LAN3) on site (SITE 1, SITE 2, and SITE 3) can access each other through the routers (R1, R2, and R3) and LAN2 in Site 2 will have internet connection via Site 1 using Route Policy.

i. Go to LAN>>General Setup, click Details Page under LAN3.
j. Enter IP address 192.168.3.1 and subnet mask 255.255.255.0
k. Under DHCP Server Configuration, select Disable Server.
l. Click OK to save your settings.
3. Configure a route policy for internet connection.
a. Go to Load Balance/Route Policy>>General Setup, select index 1 and tick Enable.
b. Comment as “Internet” and select Protocol as Any.
c. Select Src IP subnet and enter IP address 192.168.20.0 and subnet mask 255.255.255.0/24
d. Select Destination and Destination Port as Any.
e. Under “Send via if Criteria Matched”, Interface is LAN2 and Specific Gateway is 192.168.2.2
f. Click OK to save your settings.
4. Configure Static Routes.
a. Go to LAN>>Static Route, select index 1 and tick Enable.
b. Enter the following below:
