Hello, I have some troubles makging an l2tp connection between win2k and freesWAN/l2tpd. The IPsec connection seem to be okay, SA established. The problem comes with the ppp daemon. the error I have is : peer closing for reason 3 (Control channel already exists)
One strange thing is "auth" in the pppd command line, even if I have noauth in options.l2tpd I don't understand what is the "ip range" field in the l2tpd.conf. If I remove this field, I have peer closing connection for reason 1. I have joined my l2tpd log, l2tpd.conf and options.l2tpd . Could anybody help me ? Thank you very much for any answer.
