I have set up a new PIX 501 (with 10 VPN licenses) at home to protect
my own network. I have configured VPN via PDM for L2TP and "Cisco"

Unfortunatelly I can't yet connect to it either via Cisco VPN client
or standard Windows XP L2TP connection from outside.

Hereby I attach an excerpt from the configuration (I have removed nat
and access-list lines as this part is working fine):

Any help would be appreciated!
