Re: Connecting i5 Express to Internet

["Shannon ODonnell" <sodonnell@xxxxxxxxxxxxxxxxxxxxxxxxx>]

You have your iSeries set up with an IP Address of 74.219.167.174.    And
then you have the route set up to point back to that same IP address.  I
don't think that's going to work. That will create a closed loop that goes
nowhere I'd think.

Is 74.219.167.174 the static IP address your ISP gave you and you are
plugging the iSeries directly into that?

Do you have a router or a cable modem or something in there anywhere?

You really should not have your iSeries plugged into the web directly.  At
the very least, go to Wal-Mart and buy yourself a cheap Belkin or DLink
router to put in the middle.   That way you'll have at least a rudimentary
firewall in the mix. 

Here's what I would try...


Let's assume you are on a cable modem and it's static IP address is
74.219.167.174

Leave your *DFTROUTE set as you have it now, but give your iSeries the IP
address of 74.219.167.175.

Then don't forget to start the tcp/ip interface on your new IP address: 

STRTCPIFC  74.219.167.175

At this point it does not matter what you have in your domain and host table
unless you are wanting to set up HTTP Server or Websphere or Tomcat and/or
have someone come in from the outside to your system.

If you throw a router between your iSeries and the cable modem (or whatever
you have there that actually connects you to your ISP...) you'll need to
configure it to allow TCP/IP traffic to flow through it to your iSeries.
But that's another topic.  :-)

Go here and do a little reading...

and a router/firewall would be of help.
