Re: PC, internet, to AS400 via ISP -- no TN5250e

Jerry --

You might want to try a

        tracert <domain-name-of-your-400>

This should give you a list of all the computers that you're going
through to get to your 400 from your ISP.  You should be able to
investigate non-router types from there.
