I'm thinking about getting 2 XT8 units to have better coverage in my new apartment, but I really don't want to miss being able to route some clients through my router VPN and let some use the regular internet connection. Is this possible with the stock firmware? I can do it with my AC86U with Merlin, but it's so long since I used the stock firmware on Asus routers and I can't really find out if this is a Merlin specific thing or available on the stock firmware as well.
