Using Wired and wireless together??

Hi All

I am trying to route traffic on my Mac using both wired and wireless and both with different subnets.
I would like to send the internet traffic out of one and intranet traffic out the other is this even possible any input would be most welcome.

Thanks

As far as I know one or the other not both at the same time and why would you want that? On wireless you can change which one you want to establish a link to by clicking
on the icon and ask to join providing the signal is strong enough and the right password is used if its encrypted.

I understand what you want to do and could probably guess as to why, just not sure if it's possible. Sounds like Google might be your friend here.
