Two network adapter. The restriction on data transfer

Got a netbook and a local network via wi-fi to the Internet on it 2 adapter:

1) 3G adapter
2) Wi-FI adapter

Task:

On the adapter 2) WI-FI somehow restrict Internet access to work only the LAN

The firewall is not very suitable, because the netbook is so weak, if you have a firewall deliver, everything will start to slow down even more.

WI-FI network is organized through the ASUS router RT-N66U

Solution
I would set up restrictions on the router, especially since it already has a firewall.

I believe that You need to update Your FreeBSD at least until the branch 9.x
You have not written what You have installed on the netbook OS, what version and what tools are actually tried.
For example, on a GNU/Linux system configured netfilter is quite a bit to eat, but the management of such firewall manual.

PS: you can still make this restriction on the side of the router.
For OS sorry. Fixed, finished the

I did just changed my address wi-fi adapter manually with obviously wrong gateway and DNS (the IP and subnet mask set the same as was automatically assigned). Crutch, but it works. Can the gateway and DNS to put your local server, but I guess You don't.
Yes. a variant of this fit.
BUT only if the provider is technology IPoE, and not some L2TP, PPTP, 3Poe.
stupidly memorize settings given by the provider and is it a gateway to write your. DNS to replace, I think not necessarily. - winfield40 commented on October 3rd 19 at 03:42

Maybe I misunderstood, but — on the router create a guest Wi-Fi network with the prohibition of access to the Internet and connect to her laptop?
The router's settings allows.
