wireless-network

I have the following setup:

modem + router - - - - -Ubuntu box on master mode.........wireless devises. Ubuntu machine connects to Internet on wired network. I've dhcp3-server, masquerading, and wireless card with master mode on Ubuntu box. The issue is Ubuntu connects to the router on NAT. The wireless devises connect to the Ubuntu box on a NAT too (though different). SO my wireless devises are behind two NAT networks. The solution I am looking for is Ubuntu should forward dhcp requests to the modem+router, and Ubuntu should act as a switch or a bridge that allows wireless devises to connect to the wired network. So the modem+router should act a main router.
