tunl VS wireguard-go

Source

is this (https://github.com/pjvds/tunl) yours? Cannot find the github.com/urfave/cli/v2 repo

Would you accept https://github.com/WireGuard/wireguard-go/blob/master/tun/ne... as a solution? =)

Maybe https://github.com/cloudflare/boringtun or https://github.com/WireGuard/wireguard-go ?

It's likely just `tailscale serve https / `.

And they also support direct embedding:

I think this is built on the wireguard-go + gvisor mashup, that allows you to do this with just Wireguard:

One of my favorite applications of this is this little tool that turns Wireguard VPNs into SOCKS5 proxies (which you can selectively enable in your browser)

https://pkg.go.dev/github.com/octeep/wireproxy

They added this pull-request to wireguard-go and i assume they have already included it in their new version.

Vanilla WireGuard doesn't provide a way to run a peer in userspace that can proxy traffic between another peer and an endpoint such as a web server because you need to be privileged to do thinks like work with raw packets. However, https://github.com/WireGuard/wireguard-go is a userspace implementation of WireGuard and has recently incorporated Google's userspace networking stack. This project uses these two userspace tools to "fake" a privileged WireGuard peer that proxies TCP, UDP, and (a small subset of) ICMP. It was written as a pentesting/red team utility for my team but it can also serve as a general makeshift VPN when you don't have privileges on a box you want to proxy through.

How "scratch" do you want to go from? Do you want to write your own virtual network driver, or do you want to use an existing driver like Wintun? Either way learning about Wintun would be a good start. Then there's the protocol, regardless of what language you learn, the wireguard-go implementation is a very good example of how to implement a secure protocol with modern language.

wireguard-go (the official userspace impl in golang) can do this since several months back. It uses gVisor's netstack as a tcp/udp provider to forward connections to its peer.

Here's a demonstration of both a http-client and a http-server running over wireguard (a poor man's QUIC): https://github.com/WireGuard/wireguard-go/tree/master/tun/ne...

fly.io wrote about such setups not long ago too: https://news.ycombinator.com/item?id=26315695

And tailscale.com uses a similar setup (with netstack) on non-Linux/xBSD platforms: https://news.ycombinator.com/item?id=28261683

I think you can try wireguard-go,

It's in a PR here: https://github.com/WireGuard/wireguard-go/pull/11/files

Which mentions:

It actually looks useful, there's something similar in wgtypes, and I wanted to use it recently [0] but that package unfortunately doesn't expose a way to write it out to a string/buffer, so I ended up almost replicating it.

(There's a lot of ways of presenting/parsing/constructing the same config options there! I'm sure if I were more fluent in Go there's some more succinct way.)
