But a bridge would work. There is more then one way to do things. Using bridging instead of two subnets and forwarding rules has some advantages, depending on exactly what you are trying to do. It has definite advantages if you have more then one machine on the wired side of the laptop, and you want the machines on the wireless side to easily talk to them. Using bridging, you can put everything on the same subnet. You should also be able to use one DHCP server and DHCP for the entire network. (DHCP packets should travel across the bridge without any problems. I am not sure, but I would expect it to also use less resources on the laptop, because you would only have to examine incoming packets for the bridge IP address. Everything else can be passed to the other interface(s) of the bridge. But you also have the option of writing IPtables rules to limit this.
