Tor now has a build-time option to optionally include a helper script that
has upnp and/or nat-pmp functionality. This helper script further needs to
be enabled by setting a Tor configuration option (PortForwarding) to
enable the feature at runtime.

When that option is set on a build that supports it, and the router
supports and is configured to allow upnp configuration, only then will
automatic port forwarding be attempted.

It is my general recommendation to always disable upnp everywhere,
but that's beside the point here.
