Basement Plumbing/Venting

I'm going to start on a basement remodeling project very shortly. I'm OK with relocating the basement drains (just a lot of work to bust-up concrete), but I'm not sure how to do all the venting. The first floor vents are not visable from the basement. Can I just vent to the outside through a wall (the basement is walkout) or di I need to find the vent stack for the rest of the house?

Any advice would be greatly appreciated.
Thx

The vent in most places can go on the outside, and up through the roof.

Or sometimes you can find somthing like a closet that you can put a vent through.
