RE: AS/400 as a DHCP client? -- MIDRANGE-L

I am already sharing my first cable modem with my whole network using Winproxy. 
 I wanted to
dedicated another modem to the 400.

I also have the firewall licensed program that I have used before.  I know it 
stinks, but it would
have worked for what I want to do.

The cable modems are usually configured to talk to only a single NIC card or
perhaps a couple cards.  It depends on your cable company.  With mine, I can
get several.  The idea is to get your PC and your kids pc over the same
cable modem, while relieving you of the burden of carrying an extra $10 in
your checkbook every month.

You probably _could_ get your AS/400 to do this - you'd need the NIC
address, and I'm not quite sure how you'd do this on an AS/400.

BUT DON'T DO IT THIS WAY!!!!  BIG SECURITY PROBLEM!!!

If you did that, you would essentially be putting your AS/400 directly on
the internet - a VERY dangerous (although easy to implement) solution.

You should run a proxy server at home.  Depending on what you want to be
able to do with your AS/400 and the internet, it ranges from very easy to
moderately difficult.  If you only want to get from your AS400 to the
outside (ex: telnet or FTP, establishing a connection from your as/400 to a
machine on the outside) you can do this very easily with Win98 and it's
built in Internet Connection Sharing.  This can take care of _most_ small
scale situations, and you can save yourself the extra $10/month that your
cable company would want to charge for the extra machine.

If you want to get at your AS400 from the internet, the level of difficulty
varies depending on what you want to do.  If all you want is telnet and you
don't care about encryption, you can do that with Win98 as the proxy server
using ICS (you need to do some registry tinkering to get an inbound port
mapping).  FTP gets tricky (Win98 ICS probably won't be able to pull it off
due to the difficulty of active/passive FTP), and Code/400 gets _very_
tricky.  But - you _can_ do it with a commercial proxy server product like
Wingate (so far I've been able to get everything to work through Wingate).

I run an AS/400 time sharing service over the internet, and my company also
provides AS/400 to Internet consulting services.  So, I've already suffered
through a lot of these problems.  Please contact me directly if you need
more information.

Subject: AS/400 as a DHCP client?


I have a cable modem that I want to use to provide temporary access to my
AS/400.  Since the cable
company has never heard of an AS/400, I have to set this up myself.

On my PC, I just set the network card to "optain IP Address automatically",
and I guess the network
card uses the cable companies DHCP server.

Can I config my AS/400 to do this?  I have both an IPCS and an ethernet
card.  V4R4.
