The side the doors open towards is the outside. Think of it like emergency exit doors, they always swing outwards so that in a rush, people can just push it open. (or if you prefer you can use a less weird comparison to help you remember)
If you build gates facing only one direction from your pali, always build them facing out (doors swing to the outside of your claim). But with the visitor debuff, there's theoretically no reason not to build at least one door facing in, so you can unlock and get inside if you're aggro'd.
