connet itself doesn't have a notion of public share at all - you need clients/peers on both ends (destination and source) to "project" a remote service. connet.dev do enhance this, by running the source clients publicly, but you need to specifically enable this, and it is best used as a break-glass option, since obviously makes things less-private.

In any case, zrok.io is cool, it is certainly more mature and feature rich project.
