I tried to use both the default and a custom one, and setting the guest permission for both to be able to see AND enter the board, and yet, no matter what combination of permissions I tried for guests, the guests can only at most see the board but never enter it...
Anyways, it doesn't really matter anymore, my original goal was go create this 1 board that did not show in the board list for anyone, but yet could be entered by everyone, I use a portal system and one of my blocks has a navigation tab for the threads inside this specific board, so hiding it from the board list would decrease unnecessary clutter. But when i tried to do that for the other groups, it didn't work either, if they can't view the board in the list, they can't enter it either even if they have permission to enter it... So solving my guest problem is mute since the enter permission is dependent on the view permission, which makes my original goal unachievable...
Sorry for the trouble
