Not only is UPnP a security risk, it'll work only if a user has an IP that can expose ports. IPv4 addresses are becoming rarer on home networks and CGNAT connections can't expose ports even if one turns on UPnP.

Universal plug and play You can enable it in Qbittorrent's settings

Something you shouldn't use. UPnP means programs can open ports automatically without your input which is a big security risk.

UPnP is widely considered to be a significant security risk, just FYI. Because it allows any random device on your network to poke holes in your firewall whenever they want. You should go disable it on your router.

Plus UPnP doesn’t work in a lot of configurations. CGNAT, for instance, blocks UPnP.
