The title says it all. I've configured an IPSec IKEv2 connection between a Strongswan server and a Windows 7 workstation and I'd like to use compression if possible.
The config on both sides is dead simple and uses public key authentication (machine certificate on the workstation) :
conn rw
left=1.2.3.4
leftid=example.com
leftcert=cert.der
leftsubnet=0.0.0.0/0
leftfirewall=yes
right=%any
rightid="C=FR, O=Example Company, CN=workstation"
rightsourceip=2.3.4.5
rightdns=6.7.8.9
keyexchange=ikev2
esp=aes128-sha256
ike=aes128-sha256-modp2048
compress=yes # compression is enabled
auto=add
Yet, I always see "Compression: 0 %" on the Windows client, and a search for "windows ipcomp" doesn't produce any relevant results like an official MSDN page, only this page from 2010 claiming that Windows (which one?) doesn't support IPComp.
Did anything change since then, do the newer versions of Windows support it (finally a decent reason to upgrade to this Windows 8 crap) ?
