[janusloo]

What's the feature 🧐

Hi, thank you for creating this amazing software to connect to any VPN services. really useful! ;-) I would like to know if you can support QUIC Obfuscation feature from Mullvad for better security? I don't know if this is technically feasible for gluetun.

Thank you for your time and effort! Thanks in advance!

This is pretty exciting, I'll get to it (probably 2026 though)

Notes to self:

1. Read https://datatracker.ietf.org/doc/rfc9298/
2. Inspire or use directly https://github.com/quic-go/masque-go
3. Figure out how to plug wireguard through that udp proxy, probably a bit hard
