When you have multiple WAN lines connecting to the internet, and there is not enough WAN port on the router, you can increase the WAN number to connect to multiple WAN lines.
For example, when there are 3 WAN lines online, the WAN number can set to “Use WAN1, WAN2, WAN3, and the rest are LAN ports”. Then WAN1, WAN2, WAN3 correspond to WAN1, WAN2, WAN3 on the router panel.
Set LAN Number
In the same way, the number of router LAN ports can be set under this menu. The LAN1, LAN2, and LAN3 ports on the panel can be set to the physical interfaces of LAN1, lan2, and lan3 in the corresponding interface overview.
In the above example, three WAN ports have been set, and two LAN ports are left. In this case, “LAN1, LAN2 is LAN1 and LAN2 on the corresponding panel” can be set under the number of LAN ports. It is also possible not to set the number of LAN ports, but at this time, the router WEB interface is displayed as a LAN port, that is, the LAN port is composed of LAN1 and LAN2.
1) You need to reboot the router after set WAN or LAN numbers. The WAN/LAN port configuration will still take effect after restored the factory default settings.
2) When setting the number of LAN ports, the intranet will be disconnected temporarily.
3) After setting the number of LAN ports, the general announcement, DHCP, PPPoE server, and intranet setting page will be changed accordingly. The LAN port selection will be given, and the LAN port will be selected by default.
4) When your internal network needs to isolate the wireless network from the wired network physically, it is recommended to use two independent LAN ports to connect the wired LAN and the wireless LAN respectively.
