Proxying WFC

[trance]

At the moment, I'm stuck with a USB broadband modem which I cannot link or bridge to a WLAN card, and hence cannot share to the wireless network with which I want to use my DS with. I haven't had the resource to get a Ninty Wi-fi adaptor, and was wondering if there was any particular way I could route the traffic with the wireless point I have and this computer.

Of course, there's no proxy setting in the WFC setup, but can I use any other details in that setup to achieve this?
