Thanks a lot for the detailed explanation. While we have become a bit
off-topic (more of the why then the how) in regards to wireguard, I
think above explanation is important.
Wireguard's purpose is to be a secure VPN tunnel and I personally would
love if we can add "reliable" to its feature list. However that would
need more advanced support, like obfuscation is providing.
I'm not saying obfuscation is the only method, but compared to
a DPI with statistical analysis, I think we are pretty far away from
being reliable in hostile networks. Maybe extending wireguard with
obfuscation is out of scope of this project, but then it might be an
idea to wrap the wireguard traffic into other protocols.
I'm not sure how much wireguard depends on the IP/UDP layers, but
assuming it only uses it for payload, maybe it makes sense to
wrap wireguard into HTTP, HTTPS, SMTP (+TLS), IMAP(S) or even DNS
(slow). I am aware that there is a variety of tools out there that
handle some of the tunnel ideas.
Given that all of these approaches are actually rather trivial to
implement, is there any easy way to grab the outgoing wireguard packets
without the need of creating n artifical local UDP endpoints?
