WIN2k Client can't connect

[r.kate]

Hi ,

I have a pix 515 UR and I am using WIN2k to establish a l2tp vpn connection over ipsec .I am getting this message at the pix .

ISAKMP: authenticator is HMAC-MD5IPSEC(validate_proposal): invalid transform proposal flags -- 0x0 .

Can anyone guide what might be going wrong .

Thanks

Raj

The very last debug output in this link (http://www.cisco.com/warp/public/110/l2tp-ipsec.html) shows that you might be missing the "mode transport" command. Can you verify your configuration with what is shown here?
