EmployeeHi antonym ,
Sorry, I see your question is from February but I wasn't notified of it, so I am only just coming across it. The answer to your question is a little complex, but you actually can proxy traffic (ie, use LTM functionality) but you must use another network interface to send that proxied traffic out from. Then after the pool member's response, ensure that the traffic "returns back down the VXLAN tunnel" as you put it, without changing the 5-tuple (src ip, dest ip, src port, dest port, protocol).
It's complicated but it does work. That said, I just tell people to use the GWLB when they want ASM/AFM functionality, because that's what it's intended for. Hopefully that makes sense and sorry this answer comes so late!
