	I think my problem is a routing problem as I have been able to establish
the PPP link.

Yes that is exactly what I am doing. And everything works fine as far as I
can tell.

Yes I get this exactly, with the different ip numbers as you mentioned.

I have not gone that far yet as for automating the log on. I just got to
the point in the Howto: that I could connect to my ISP and then I got stuck.

The above files are just like yours with the exception of my ISP's and DNS
entries.

No I am not running the HAMM version yet. I wanted to get everything done
in the stable version before moving up to the HAMM verison.

This is where my problem starts. When I ping my ISP I get good pings but
only 204.47.44.4, but if I try the name, dallas.net, I get nothing as I
have not be able to establish a link to the DNS. I can ping my own machine
and my ISP by IP numbers only.

Thanks again, Bill. This was my first question and I wasn't sure how to
exactly ask it. But you have given me some ideas where to look.
