Eater barriers only ever really defend against a few types of collision. That’s just a function of how eaters work—they only ever eat a small subset of things that can be projected at them.
I don’t think anyone has ever created an impermeable wall in the GOL. I am pretty sure that such a thing is impossible—though AFAIK, that has never been proved.
