Create network bridge using my mac mini. Not router

I would like to bridge the network between the ethernet and the wireless on my mac mini. This is so I can access my networking using the N wireless through my mac mini instead of my router's G wireless. I would like to get the dhcp address from my router so I am on the same network. This is so I can access my server that is on the wired network using AFP. In other words use my mac mini as a Access Point.

For you networking buffs, I would like to use my mac mini as a bridge on layer 2, NOT as a router on layer 3.

This makes the mac mini act as a router not a bridge. (mac mini runs DHCP gives out 10.* address). This clearly won't work.

Mac mini runs OSX 1.6
MacBook pro runs OS 1.5

Easiest solution without spending money that I have thought of is to set up a windows VM do the bridging for me.

..wrong on so many levels

Not related to the VM idea. Any one know how to turn off the DHCP server on internet connection sharing?
