OK, after the second reading I finally got it :-))

"You might have already tried this and found the VPN clients can't connect
to the Internet through the ISA Server. The reason for this is that the VPN
clients cannot act as SecureNAT clients. There is no way for you to
configure the VPN client to use the internal interface of the ISA Server as
its default gateway. The default gateway is already set when the VPN client
connects and its clearly not the ISA Server's internal interface. While the
details are a bit more complex than this, the fact remains that there is no
solution to this problem; you will never make the VPN client a SecureNAT
client."

Thanks Tom!
