I think they can aggro you through open gates if they're in direct line of sight of your character, unless this was changed. This can be worked around by building a small fence in front of the gate inside the pali to break the line of sight.

Having gates open might lead to some stuff like bears walking in. Its an unpleasant surprise. I'd suggest to keep gates shut on all times.
