NAT Traversal with libp2p

d-central · September 27, 2019, 9:02pm

Hey folks,

I am currently working on a simple chat application for a prove of concept of different NAT traversal approaches. Under concepts there is a kind of waterfall approach described, to test different NAT traversal techniques. But it seams like thats all not really implemented jet and circuit relay is mainly used.

Am I right here or am I missing out on something ?

Best regards and thanks for any help !

Sorry nobody replied. I also am confused about NAT traversal of p2p networks. I’m interested in adding a transport built around https://github.com/torproject/torspec/blob/main/control-spec.txt#L1660-L1836

Later, rust will have library(direct?) access to an implementation.

Edit: LoL, I see what you did there… and stop trying to be smarter than Alpha Go.

This GitHub issue tracks the status of NAT traversal capabilities across libp2p …implementations and platforms. See [Hole Punching](https://github.com/libp2p/specs/blob/master/connections/hole-punching.md) document for greater picture. Please comment below to suggest additions or corrections. --- ### Projects The following projects combine various protocols from the table below to achieve NAT traversal: - Project Flare - [project proposal](https://github.com/protocol/web3-dev-team/pull/21/files), [Golang tracking issue](https://github.com/libp2p/go-libp2p/issues/1039) and [high level architecture](https://github.com/libp2p/specs/issues/312#issuecomment-880762775) - Transport Protocols - TCP - QUIC - TURN-like Protocols - circuit relay v2 - Signaling Protocols - Direct Connection Upgrade through Relay - STUN-like Protocols - AutoNAT - Other Protocols: - multistream-select v1 simulataneous open - AutoRelay - WebRTC star - Transport Protocols - WebRTC star flavour - Signaling Protocols - WebRTC star signaling protocol - HOPR Connect - Transport Protocols - WebRTC HOPR connect flavour - STUN-like Protols - STUN - TURN-like Protocols - circuit relay inspired HOPR connect flavoured - Signaling Protocols - HOPR signaling messages - [Project proposal: browser nodes can connect to any node out of the box](https://github.com/protocol/web3-dev-team/pull/70/) - Transport Protocols - Websockets for signaling communication - WebRTC for data communication - TURN-like Protocols - circuit relay v2 - STUN-like Protols - STUN - Signaling Protocols - ? ### Protocols None of the Protocols below enable NAT traversal by themselves. Instead combinations of these protocols do. | | specification | go-libp2p | js-libp2p/browser | js-libp2p/NodeJS | rust-libp2p | |---------------------------------------------------|----------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------|----------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | **Transport Protocols** | | | | | | | TCP | | [go-tcp-transport](https://github.com/libp2p/go-tcp-transport) + [port-reuse](https://github.com/libp2p/go-reuseport-transport) | | [js-libp2p-tcp](https://github.com/libp2p/js-libp2p-tcp) | [rust libp2p-tcp](https://github.com/libp2p/rust-libp2p/blob/master/transports/tcp/src/lib.rs) + [port-reuse option](https://github.com/libp2p/rust-libp2p/blob/385af35047e4936bc6e7a1d76dc01a58e7bbb6cc/transports/tcp/src/lib.rs#L205-L302) | | QUIC | | [go-libp2p-quic-transport](https://github.com/libp2p/go-libp2p-quic-transport) | | | https://github.com/libp2p/rust-libp2p/pull/1334 | | Websockets | | [go-ws-transports](https://github.com/libp2p/go-ws-transport) | [js-libp2p-websockets](https://github.com/libp2p/js-libp2p-websockets) | [js-libp2p-websockets](https://github.com/libp2p/js-libp2p-websockets) | [rust libp2p-websockets](https://github.com/libp2p/rust-libp2p/blob/master/transports/websocket/src/lib.rs) | | WebRTC | | | | | | | * WebRTC spec compliant | https://github.com/libp2p/specs/issues/220 | | | | | | * WebRTC star flavoured | | via [go-libp2p-webrtc-star](https://github.com/mtojek/go-libp2p-webrtc-star) | via [js-libp2p-webrtc-star](https://github.com/libp2p/js-libp2p-webrtc-star) | via [js-libp2p-webrtc-star](https://github.com/libp2p/js-libp2p-webrtc-star) | | | * WebRTC HOPR connect flavoured | | | | via [hopr-connect](https://github.com/hoprnet/hopr-connect) | | | | | | | | | | | | | | | | | | | | | | | | **TURN-like Protocols** | | | | | | | circuit relay v1 | [v1](https://github.com/libp2p/specs/blob/master/relay/circuit-v1.md) | [go-libp2p-circuit](https://github.com/libp2p/go-libp2p-circuit) | via [js-libp2p](https://github.com/libp2p/js-libp2p/tree/master/src/circuit) | via [js-libp2p](https://github.com/libp2p/js-libp2p/tree/master/src/circuit) | [rust libp2p-relay](https://github.com/libp2p/rust-libp2p/blob/master/protocols/relay/src/lib.rs) | | circuit relay v2 | [v2](https://github.com/libp2p/specs/blob/master/relay/circuit-v2.md) | [go-libp2p-circuit](https://github.com/libp2p/go-libp2p-circuit) | | | https://github.com/libp2p/rust-libp2p/pull/2059 | | circuit relay inspired HOPR connect relay | | | | via [hopr-connect](https://github.com/hoprnet/hopr-connect) | | | | | | | | | | | | | | | | | | | | | | | | **Signaling Protocols** | | | | | | | WebRTC specific or generalized signaling protocol | https://github.com/libp2p/specs/pull/159 | | | | | | Direct Connection Upgrade through Relay | [DCUtR spec](https://github.com/libp2p/specs/blob/master/relay/DCUtR.md) | https://github.com/libp2p/go-libp2p/pull/1057 | | | https://github.com/libp2p/rust-libp2p/pull/2076 | | WebRTC star signaling | | client via [go-libp2p-webrtc-star](https://github.com/mtojek/go-libp2p-webrtc-star) | client via [js-libp2p-webrtc-star](https://github.com/libp2p/js-libp2p-webrtc-star) | client + server via [js-libp2p-webrtc-star](https://github.com/libp2p/js-libp2p-webrtc-star) | | | HOPR signaling messages | | | | via [hopr-connect](https://github.com/hoprnet/hopr-connect) | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | **STUN-like Protocols** | | | | | | | STUN | | | | via [hopr-connect](https://github.com/hoprnet/hopr-connect) | | | AutoNAT | https://github.com/libp2p/specs/issues/180 | https://github.com/libp2p/go-libp2p-autonat | | | https://github.com/libp2p/rust-libp2p/pull/1672 | | | | | | | | | | | | | | | | | | | | | | | **Other Protocols** | | | | | | | multistream-select v1 sim open | [connections/simopen.md](https://github.com/libp2p/specs/blob/master/connections/simopen.md) | https://github.com/libp2p/go-libp2p/issues/712 | | | https://github.com/libp2p/rust-libp2p/pull/2066 | | AutoRelay | https://github.com/libp2p/specs/issues/181 | [go-libp2p/autorelay](https://github.com/libp2p/go-libp2p/blob/0741d17496aa96a62c4283c01ae5009221bed621/p2p/host/relay/autorelay.go) | | https://github.com/libp2p/js-libp2p/issues/699 | | | UPnP | | via [go-libp2p-nat](https://github.com/libp2p/go-libp2p-nat) | | | | --- _Keywords for search engines: hole punching, TCP, QUIC, WebRTC, UPnP, ICE, STUN, TURN, meta_
