Do you love bittorrent?
Set your client to use any standard TCP+UDP ports: 6881-6889
Open/forward all of these ports. Set your bittorrent client to one of these, for incoming connections.
Basically, make sure that ports 6881-6889 are open, and that your machine is directly accessible on the internet via these ports.
This makes you easier to find by other peers. If your ISP puts you behind CGNAT (carrier grade NAT), ask for a dedicated IP address. My ISP gives me public IPv4+IPv6 subnets.
