TL-ER7520G has five physical network interfaces, supporting 802.1Q VLAN, you can add multiple virtual interfaces, through custom port types and parameters to achieve a variety of networking requirements. Below we introduce the common use, TL-ER7520G Internet Configuration method, mainly includes the following types:
1 WAN port + 4 LAN ports with the same network segment
2 WAN ports + 3 LAN ports with the same network segment
1 WAN port + 4 LAN ports of different network segments
You can select the desired type based on your networking requirements.
Type 1: 1 WAN port + 4 LAN ports with the same network segment
The network topology for this type of requirement is as follows:
1
, Login vro interface
The TL-ER7520G is not factory-enabled with DHCP server and must be managed through Interface 5. Connect the management computer to the vro5 interface No. 5, and manually configure the local connection of the computer as 192.168.1.X (2 ≤ X ≤ 254 ). Open your browser and enter the vro management address 192.168.1.1. Enter the default user name: admin and Password: admin.
