The same rules apply for post as any other position on the floor in theory. You cannot put your hands on the ball handler to hold or direct an opponent. You cannot hold, push, grab, restrict and opponent and their movement. So a forearm to hold a player in place is illegal. Now will these get called without any consideration to other things? Not necessarily. But if you want to teach a player the right things, have them hold their position and move their feet. Any use of their arms or legs to contact and opponent is not legal on many levels.

I hope that helps a little, but I I would think to help you is to ask specific things that are either being called or not being called.

Peace
