I have 5 IP devices that I need to be joined into a LAN (lanA). And I need this LAN to be connected wirelessly to the (wireless) router (lanB).

So that my LAN of 5 IP devices appears as a single IP to the outside network (routerX network).

Devices of lanA use static IP addresses.

So basically I need a NAT-capable device that has wired connection to my devices, and wireless uplink connection to the main LAN. Are there routers that can be configured this way?

doesn't the router on LAN-B function as a NAT firewall? if so than all you're really looking for is a router or access point that can operate in bridge mode for LAN-A, right? – Xantec Jun 15 '11 at 20:36
    
I need to hide my (lanA) devices from lanB. lanA shall be a subnet, not a segment of the lanB. So what I need is a wireless router with Client Router mode. (this is the answer) – user58396 Jun 15 '11 at 21:00

Buy any DD-WRT compatible router, and use bridged mode. You may already have a compatible router.

You can check router compatibility here

Here's a list of supported devices

Instructions for setting up bridged mode

DD-WRT is a custom firmware, based on Linux, that runs on many cheap and popular routers. It gives the router the functionality of network devices costing thousands of dollars.

bridged mode (client bridge) will add my devices to the lanB LAN. What I need is DD-WRT "Client Mode" (or "Client Router" mode). – user58396 Jun 15 '11 at 21:01
