L2TP/IPSec PreShared Key VPN

ipsecl2tpvpn

I tried to setup a L2TP/IPsec VPN server with PSK authentication according to this tutorial on a Ubuntu server but there is a problem when I'm trying to connect to this server with a Windows 7 client. I can't connect using PSK however it works when I use certificate for authentication. I don't know why? Any idea?

Thanks

Windows 7 has some different settings from Windows XP which can affect compatibility; the most notable ones are the removed support for the MS-CHAP V1 authentication protocol (only MSCHAP V2 is supported) and different encryption settings for L2TP/IPSEC (as documented here).

I don't know how this applies to Ubuntu, but maybe it can point you in the right direction.
