Forgive the ignorance, but I am guessing that the ASUS Router needs to be in "router" mode to be able to provide this functionality? I currently have the RT-N66U, but I have it acting as an AP behind my wired router. I have been curious to dabble with VPNs
Instead of using it as an AP double NAT it behind your primary router then you can experiment with the VPN. I run a VPN in a double NAT setup and it works fine running a VPN client.
