The first entry in Figure 3-30indicates that: This is a Multi-Nets NAT entry named tplink1. The subnet under the LAN port of the Router is 192.168.2.0/24 and this entry is activated. After the corresponding Static Route entry is set, the hosts within this subnet can access the Internet through the Router via NAT.

Note:

●Multi-Nets NAT entry takes effect only when cooperating with the corresponding Static Route entries.

●The DMZ port will display in the drop-down list only when the DMZ port is enabled.

● For detailed setting of subnet mask, please refer to the Appendix B

Network Requirements

The LAN subnet of TL-ER6120 is 192.168.0.0 /24, the subnet of VLAN2 under a three layer switch is 192.168.2.0 /24, while the subnet of VLAN3 is 192.168.3.0 /24. The IP of VLAN for cascading the switch to the Router is 192.168.0.2. Now the hosts within VLAN2 and VLAN3 desire to access the Internet.

The network topology is shown as the following:
