Academic exercises aside, the only reasons I can think of to use a |
| 11 |
general-purpose computing device for this purpose instead of a simple |
| 12 |
switch would be a) cost, or b) to do something that the switch can't do, |
| 13 |
such as firewall. If you really just want a switch, and the money isn't |
| 14 |
a big deal, go with the switch. |

That said ... strictly speaking, what you're asking for is a bridge, |
| 17 |
which may not be the easiest way to accomplish your ends, nor the most |
| 18 |
flexible configuration. Maybe consider this easy approach: |
| 19 |
|
| 20 |
- - create a separate network for each NIC (maybe 192.168.2.0 and |
| 21 |
192.168.1.0), and give each an appropriate IP address (maybe 2.1 and |
| 22 |
1.1 respectively). |
| 23 |
|
| 24 |
- - enable IP forwarding, and NAT if appropriate for outbound traffic |
| 25 |
(sounds like you already know how to do that). |
| 26 |
|
| 27 |
- - Make sure your DHCP server listens on each of those networks and has |
| 28 |
an address pool for each. I run mine right on the gateway, and ensure |
| 29 |
that it doesn't listen to the public address. |
| 30 |
|
| 31 |
That's basically it. A big advantage of this is that if you want, now |
| 32 |
you can easily isolate one of those segments to create a DMZ for a web |
| 33 |
server or a playstation or something else fun. |
