(ASCEND) Problem with L2TP, between Ascend TNT and Cisco 1603 R

[Atto Lorenz <alorenz@CYBERNET-AG.net>]

Hello,

i have a problem with setting up L2TP between an Ascend TNT and a Cisco 1603
R. Something is going wrong during the tunnel initiation between the
routers. The Cisco receives package for the tunnel initiation, but then
something is going wrong. Has someone experience with L2TP between a TNT and
a Cico-Router?
Thanks for any help.
