With a lot of ugly hacks. Why would you want to do that?

I'm fairly certain - but no more than that - that you could bridge those
four interfaces together, and assign whatever is attached to them your
external interface as a gateway.

Either way, you should consider using those four NICs to create separate
subnets - which has both advantages and disadvantages, of course.
