It seems that Windows Server 2003 is initiating the connection, and
not your FC4 client. Are you sure you did a:
ipsec auto --up L2TP-PSK ?

Or did those log events occur _after_ you could not connect? In other
words, have you looked at what happened earlier in the logs?

I just realised that I forgot to put an example for PSKs on my webpage,
for when Linux is used as an L2TP/IPsec client. Sorry about that,
but you figured it out anyway because your .conf file looks exactly
like mine :-).

You can delete the first one (if you are
I would recommend : PSK "presharedkey"

if the Linux client is behind NAT.
