Which ports can/should I open to allow incomming connections?

I understand that Acestream uses a variant of BitTorrent to work. With BitTorrent, to establish a swarm effectively both outgoing and incoming connections are necessary.

I'm using aceproxy on my notebook now, which only has full IPv6 access, IPv4 is working with NAT+IP masquerading. Which incoming ports could I forward from my router to my notebook to let aceproxy/Acestream handle incoming connections? Are these ports configurable somewhere?
