A nodraw that bullets can go through?

[Nohbody]

Could you guys help me out? I want an invisible wall that players cannot go through but their projectiles can. I tried searching but this seems really specific. Thanks in advance.

And while youre here, could somebody point me in the right direction for an entity that teleports players? Thanks for that too
