Your ISP purposely rotates IP numbers so that people will not have their
home machines as servers on the internet.  There are many reasons for this
including porno, warez, & spam problems caused by casual servers on the ISP
s domain.

If you want your AS/400 serving on the net then you'll want a registered
domain name and a fixed IP address so the world can beat a path to your
doorstep.  Do this in cooperation with your ISP.  He'll charge you more, but
then, he offers you more, including technical advise so that your site runs
properly. Its neither a bad deal nor a rip-off.

Just to add a couple of things to what the others have said.
1) If you have a dynamic IP from your cable ISP, you can use a service such
as www.zoneedit.com to provide DNS on a domain for you. Then when your IP
changes they update their records and your programmers can still access your
network.

2) I don't know about your cable ISP, but the cable provider here did not
think too much about security when they engineered things. Be very careful
with what ports you open up. Of course the best way to handle this would be
to implement a VPN. But if you are trying to do this cheap I would
recommend writing a telnet exit program that authenticates users. This way
you can check their user id (it is passed if they use a TN5250e compliant
telnet client and use auto sign-on) to see if they are on a list. Since
non-TN5250e telnet clients don't pass this info, the AS/400 will close the
connection even before it would display a sign on screen. This can help
protect you from hackers, since the vast majority out there won't be using
this kind of telnet client.
