We'll see if we can slip it in somewhere.

This is a good, routable ip that should be good. Maybe releasing it in
Win98 before switching to Dachstein would fix the problem.

This is a non-routable private class ip..... this should _not_ be a
good ip address. Maybe a call to your ISP would resolve this,
some ISP's map to MAC addresses on the connected NIC causing
strange errors like this.  But the DENY's below seem to indicate that
the DHCP server is trying to send more info, but that it is blocked by
the firewall. I would think that this might well be the problem.

This 172.16.x.x. is another private class block, it appears to be a DNS
server returning a request from your firewall/network.

All in all, your ISP is doing unusual things with trying to run their
service(s) servers on RFC private class ip's. You can open these
private blocks in the firewall and I would assume things would work,
but I would be _very_ unhappy about it..... other private networks on
the same public block that don't seem to contain their private traffic
could cause problems with yours if these blocks are open.

If linux isn't the answer, you've probably got the wrong question!
