Hi HN,<p>during December 2022, we are running a measurement campaign to investigate decentralized NAT hole punching success rates using the libp2p DCUtR protocol [0]. Ubiquitous peer-to-peer connectivity is still a big challenge. If successful, NAT Hole Punching can be a game-changer for decentralised applications and networks!<p>For that we are searching for participants who would run a lean client on their machines that performs hole punches with other peers and then reports back the results to our server. We explained the measurement methodology in this video [1] and the linked repository above.<p>Running such a client certainly has privacy implications which are documented here [2]. Most importantly, we record public IP addresses, successful NAT port mappings, and the login router page (to draw conclusions about which routers work better than others).<p>Optionally, you can also sign up here [3] and provide additional information about your personal network and receive a personal API key so that we can link your data to your information. Obviously, this has stronger privacy implications - but this is totally optional.<p>The most frictionless way to participate is to head to the releases page [4] and download a client that suits your platform and needs. No sign-up required.<p>[0] <a href="https://github.com/libp2p/specs/blob/master/relay/DCUtR.md" rel="nofollow">https://github.com/libp2p/specs/blob/master/relay/DCUtR.md</a><p>[1] <a href="https://www.youtube.com/watch?v=fyhZWlDbcyM" rel="nofollow">https://www.youtube.com/watch?v=fyhZWlDbcyM</a><p>[2] <a href="https://discuss.libp2p.io/t/call-for-participation-nat-hole-punching-measurement-campaign/1690" rel="nofollow">https://discuss.libp2p.io/t/call-for-participation-nat-hole-...</a><p>[3] <a href="https://forms.gle/h1ABCpS87jYmg9a48" rel="nofollow">https://forms.gle/h1ABCpS87jYmg9a48</a><p>[4] <a href="https://github.com/dennis-tra/punchr/releases/tag/v0.9.0" rel="nofollow">https://github.com/dennis-tra/punchr/releases/tag/v0.9.0</a>
