D-Link DFL-1500 [82/271] Objectives
Part III
NAT & Routing
D-Link 74
8.2 Objectives
1. We need to let DFL-1500 knows how to forward the packets which is bound for financial department (192.168.50.0/24).
2. The network administrator plans to solve the problem by subscribing the second link (ISP2). He hopes that all the packets
from the General-Manager-Room (192.168.40.192/26) will pass through the ISP2 link instead of the default ISP1 link.
8.3 Methods
1. Add a static routing entry to direct the packets towards 192.168.50.0/24 through the router (192.168.40.253).
2. Add a policy routing entry for the packets coming from General-Manager-Room department (192.168.40.192 /
255.255.255.192) through the ISP2 link.
Two restrictions of the default WAN Policy Route: 1) As long as the subnet is directly connected to the
DFL-900/1500, it will be routed with the routing table as the priority 1. 2) For the subnet indirectly connected to
the DFL-900/1500, it will be routed to the policy route only when it comes to the default route.
