When I connect with the Dialup VPN login (icon created by install),
dials up for you and then logs in, I get the message

"either [our public IP] is an invalid VPN server address or the
authentication gateway is not loaded on the VPN server"

However if I dial in using the Microsoft dialup connection to my ISP
then use the red N in the system tray to login (using VPN dialup) I
connect perfectly.

Some of the people who will be VPNing in will not have the novell
and will therefore need to connect using the initial method.
