The next group of settings is called LAN. It includes the setup options of the router’s internal network. Particularly, the LAN IP page is for specifying the IP address the router will have on the LAN.
The DHCP Server page is about the router’s integrated DHCP server. You can specify DNS and WINS servers and a LAN gateway with addresses other than the RT-N15’s address, which is a rare option for a home router. You can also reserve IP addresses here.
There is no routing table item in the main menu, so the routing rules are specified on the Route page. The available options are sufficient for a home router.
