I have a location in a building where running an ethernet cable is just not possible. I am looking for way to get a raspberry pi to connect wirelessly to one of the AP's and convert it to ethernet. I would be plugging in the raspberry pi's ethernet to a 5 port managed switch. The ethernet port on the raspberry pi as well as the wireless need to be configured as a trunk port. My AP's can handle this, I just need help configuring the pi. I dont need DHCP or anything, I need this to be on the same LAN as my other equipment. So a transparent bridge.

LAN -> Wireless AP -> Wireless Pi -> Ethernet Pi - Switch

The Pi should not manipulate the ethernet or wireless traffic, All I need it to is just to send whatever comes in out the wireless or ethernet interface.

I have read several articles but they include maserading the ip's which I dont need.

Could someone help me come up with a solution?

You want to have a client WiFi connection to an uplink access point. The problem is, that a Raspberry Pi does not support bridging a WiFi interface used for a client connection due to a hardware limitation. For further information about this look at Raspberry Pi WiFi to Ethernet Bridge for a server?.

But as noted there you can use proxy arp as a workaround for a bridge. I suggest to use section Static configuration of proxy arp because it is simpler and just right for your use case.
