you should not have port 80 open. However, when running a BitTorrent client, you should typically have ports 6881-6889 open. But all this is only possible if you got a proper IP number, non-firewalled, no NAT. Again, this depends on your provider, your router, etc. Unfortunately, modern Internet practices are not P2P friendly…
tribler etc use uPnP so ports should open automatically unless the access point is setup wrong
