Boy,

        This is a very scary statement.  I would suggest that you think very
long and hard about putting a valid public IP address directly on your
AS/400 IF it is running any mission critical applications.  Rather I
recommend to my customers that they use a private IP address (RFC-1918) for
there AS/400 and map the connections they wish people to have from the
Internet to the AS/400 through a FireWall.  Don't map FTP or Telnet if all
you want is a SSL Web server connection.

        The use of NAT (Network Address Translation) in a Firewall product
also allows you to close and restrict access to the system, as well as
develop your Intranet independently from the ISP you choose today.  If today
use MCI and tomorrow you use IBM all that would change on your network is
the NAT map in the Firewall, and the secondary DNS resolution for
Intranet/internet name.

        Lastly, watch the VPN issues closely.  if you want to use encryption
and encapsulation over the Internet then Firewalls give you more options as
to rather the user/site has access your intranet or a specific system on
your Intranet.

        This field and technology is changing rapidly, and I support all
three technologies as a means of establishing a connection for the user, you
just need to carefully way the budget, reliability, throughput, and security
issues in making your choice.

        BUT always start with the door closed, and open it as appropriate.

        Jeff Silberberg..

>Once the AS/400 has a true internet ip address then any of the outlying
shops, or even salesmen's hotel rooms, can use AOL, ibm.net, or whoever they
usually use and just click their copy of Client Access and they have a
sign-on screen from anywhere.   There's no magic, it just happens.  The
remote support effort is almost nothing, and remote printing becomes
trivial.  It really is that simple, once the AS/400 is on-line.
