Subject: [Bloat] ECN on vpns?
Date: Mon, 30 Jun 2014 22:24:23 -0700	[thread overview]
Message-ID: <CAA93jw7VL+tS258oeAP9sL4xJWeTFABgccQ_jjCp0r2RUi=39Q@mail.gmail.com> (raw)

I presently don't have any ipsec based tunnels running (having
reverted to the much easier to setup openvpn), and we'd discussed what
the rfcs said about ecn a while back:

http://permalink.gmane.org/gmane.comp.embedded.cerowrt.devel/470

And I'd noted that encapsulation seemed to be working even further back:

https://lists.bufferbloat.net/pipermail/bloat/2011-June/000554.html

but I haven't ever got around to checking what products, if any,
actually decapsulated ECT(1) correctly back into the original IP
header.

Does anyone know if linux + strongswan/libreswan and/or other forms of
vpn encapsulation (tinq, openvpn, commercial products), are doing the
right thing presently? I would figure openvpn can't (due to doing
compression)...

I see ecn negotiation is in the ikev2 standard...
