[c-nsp] Problem with VPN to PIX

[Ted Mittelstaedt]

Hi All,

  OK I am stumped on a problem and I've looked over this config a dozen
times
and I don't know why it's not working.  I'd greatly appreciate any
suggestions
other than to run the Cisco VPN client.  (I'll shoot any smartass that
suggests
that, and no it don't work either, I already tried)

  Setup is a PIX 506 running PIX 6.3.4  VPN client is Windows XP SP2, and
also I tested with Win98 running Microsoft's IPSec VPN client.  The
clients are
configured to use IPSec/L2TP with a preshared key.  They don't work, do
not authenticate.  I get a log entry on the PIX about isakmp handshaking
starting up and that's it.
The clients just hang during the initial connection.

  The exact same PIX and same Windows clients work perfectly if I wipe
the
PIX config and replace it with a PIX config that does PPTP and change the
clients to use pptp.

  I've also tried "isakmp policy 20 group 2" with no difference.

Here's the PIX config:

Any suggestions?  This is the one config Cisco doesen't seem to have on
file
for the PIXen.  (no, I do not want to use a 3rd party generated
certificate)
