DD-WRT Client Mode Setup. How to setup Client mode on a DD-WRT Router. This mode is NOT for WIRED connections between two routers! It is a wireless connection between two routers only.
A router in Client Mode connects to another wireless Access Point (the host router). It uses its wireless connection as the WAN interface, and shares the internet connection only to the LAN ports.
It is not seen as an access point by laptops or other computers scanning for AP’s and does not accept wireless connections from client devices. The AP is not required to be running DD-WRT firmware.
The main router and secondary router (DD-WRT client mode) are on separate subnets. NAT is used between the routers. Thus, when port forwarding is needed it must be configured at both routers — not just on the main (host) router.
The router in Client Mode must use its own DHCP server to give out IP numbers, Gateway and DNS server to the devices connected to its LAN ports.
