thank you for your complete answer, but for the ipsec I know it's going to take a lot of work but you don't mention it anywhere, are you thinking about it, technically I think it's possible even if it's complicated.
But the ipsec protocol between routers and firewalls is essential in a zero trust network, it's a feature that for me will be essential when routers and firewalls are supported, but it's true that on windows android linux devices as supported today it's not important.
I wanted to know if you had thought about it or if it's on the roadmap, I didn't see it anywhere.
I really think you're the most interesting vpn project I've seen in the last few years, mullvad has moved the sector forward a lot but the revolution could come from you with mixnet.
