Thanks for your help, but it still doesn't work..
1/. If I assign the gateway address for all "other" machines to the NIC
of the "server", then those machines can ping and access the server, but
not the outside world.
2/. If I assign the gateway of the Server to the DUN IP, then the server
can no longer see the outside world. If I leave the gateway blank, then
the Server can see the outside world, but all other machines cannot.
The routing table looks like:-
Active Routes:

0.0.0.0 0.0.0.0 203.63.183.221
203.63.183.221 1

255.255.255.255 255.255.255.255 210.8.52.100
210.8.52.100 1
(Which is exactly the same as a working NT server under the same
conditions.)
203.63.183.221 = DUN port
210.8.52.100 = NIC
a) Server can see internet and LAN, all ok.
b) internet can only see DUN IP, cannot see NIC IP or any machine on LAN
c) Any machine on LAN can see NIC IP, DUN IP, but not any further on the
internet.
Note, I now have two different machines (Customers) with this exact same
problem, so whatever it is, I need a fix fast.
I am lost, any help suggestions appreciated.
