I use cisco vpn client ver 4.6 in win XP and try to connect to VPN gateway that have public IP.
My computer is connected by direct cable to a router .And this router is connected
to internet by PPPoE .
I use Cisco VPN client ver 4.6 and try to connect VPN gateway .
But It is failure.The error is 412.
But if the same computer connect to internet by PPPoE directly and the VPN client
can connect the same VPN gateway without problem .

Why do I cannot connect VPN gateway when there is router .
How can I fix it ???
Please advice .
