Part 2 of subdivided question.
>On installation, the TCP/IP properties wont let me obtain an ip address. (that box is greyed out)... Telstra assigns their ip addresses via a dhcp server on their end, this IP i assume, applies to the cable modem on my end.
this setting shouldn't be in network card properties - but in tcp/ip properties - is this NT we are talking about?
Sorry that was my mistake ... Yes NT is the o/s
My second PDC nic, which is plugged into the cable modem i.e. inside the pdc box, needs an ip address to function within the PDC, so what ip should I be assigning to it ??
|Cable | | PDC |
|Modem |----| with |---(clients)
| | |Proxy Svr |
(I'm sorry but this ascii diagram is the best i can do under the circumstances If it appears wrong it is simply 2 boxes connected by a dotted line with the word 'clients' in brackets on the end of the second connecting dotted line.)
I was under the impression that it should have the same IP address as the cable modem.
One box (PDC) containing both nic's also Back Office. ... including Exchange Server, Proxy Server, IIS4 and SQL.
The cable nic should talk to the cable modem (hopefully on the web side of the firewall) and the internal nic serves the clients behind the firewall.
Its a case of one box does the lot.
>umm, i think it would be good if you could describe how you have these different boxes connected to each other - could you draw a simple ascii diagram for us?
done as above
as for addresses, use a private address range, say 192.168.x.x for 'class b' network, or 10.x.x.x for a 'class a' network.
Do you assign an address to BOTH cards ???
As this is only one box with 6 clients, I assume a 'class b' type address is suitable
Here are your options, Bren
