how do you make a barricade to stop actors?

I want to make a wall sort of thing that stops an actor moving. I made the actor stop with a collision rule but then it wasn't able to go backwards after it hit the barricade.

please help if you know

Are you controlling the actor that hits the barricade? If not make the actor that hits the barricade have more bounciness so that it reacts when it hits the barricade.
