hi,

could anyone help me and shed some light on a problem i am having?
i am trying to setup a remote access vpn as follows

w2k client --> cisco pix 515e using l2tp/ipsec

w2k client is connected to the net via an adsl router with a lan net of
192.168.0.0 255.255.255.0 and an external ip s.s.s.s (in the debug)
pix is (d.d.d.d)

i have installed the ms cert server and have installed a cert onto the cisco
and the w2k client. i have read just about everything i can find and have
hit the following problem.

the vpn connection from the w2k client hangs and the pix seems to be showing
a debug message;
"invalid transform proposal flags"

the only ref to this error seems to point to the pix being incorrectly
configured to use tunnel mode, but i have set

"crypto ipsec transform-set trans01 mode transport"

(ike seems to be working in the debug)

im stumped and have spent 2 weeks getting this far :O(

help

Dan

debug follows;
