Thanks for your response, Ray. Hopefully I can clarify.

Yes. Originally I had Gnatbox Lite running fine on a P1 machine with no HDD. When the
changes were made i could no longer connect with Gnatbox, so I tried installing
Dachstein on the same machine. I have now also tried Eigerstein on this machine which
exhibits the same problem.
My Win98SE worksation is a totally different machine.

Essentially, as far as I'm aware, they moved my account to a different local server
network location. I'm afraid I don't know if it uses a different DHCP server, but I
have been assigned a significantly different IP address (213.107.X.X became 80.5.X.X).

I first tried Gnatbox several times, rebooting my Modem and allowing 4 hours for
leases to expire. When I had no joy I tried connecting my Win98 machine directly to
the cable modem and DHCP was resolved first time. I had previously not connected via
Windows for over 6 months.
As far as I know, my ISP is only concerned with the MAC address of my Cable Modem,
which they have on record.

Heres the route output (I found the DHCP IP above in winipcfg, although it doesn't
appear here):
C:\WINDOWS>route print

Yes on all counts. I have never had to reconfigure gnatbox in the past so I stuck
with it for a while with it's original settings but to no avail.

Thanks a lot for taking the time with this. I'm a relative newbie to *NIX and
networking but when the SysAdmin friend who installed Gnatbox for me couldn't find an
answer I had to come here. I hope the details I have supplied are of some help.
Thanks again, Roki
