Internet security and the AS/400

["Jack Mullins" <jmullins@xxxxxxxxxxx>]

Hello Everybody,

I know there has been some discussion of this in the past.  However, I would
appreciate it if I could trouble you again with a few questions.

I am setting up a dedicated connection to the internet at my office via
ISDN.  I'm going to route the internet connection directly onto my ethernet
so that everyone on the ethernet will have access to the internet.  However,
I want to protect my AS/400 which is also connected to the ethernet.  Also,
I am planning to eventually use the AS/400 as an e-mail server and possibly
HTML server in the future.  I am presently considering buying a fiewall to
protect the entire ethernet.  What other considerations do I need to
entertain and will a firewall be enough?  How safe will it be to allow
telnet/ftp access to my home users (the only users will probably be MIS for
now)?

I could use suggestions on firewall brands too.  What kind of experiences
have you had, good or bad?

Thank you,


Jack Mullins
