I`m about to completely restructure my home network and i thought if i right my plans down you guys can pick them apart and point out any problems. The main thing i`m worrying about is my plans to run an IDS on a linux box using transparent bridging and then to have a third network card with an IP address to connect to it.

This my best atempt at a diagram.


INTERNET
|
|
Cable Modem
|
|
Hardware Router and Firewall
|
|
Transparent Bridge with IDS ----------
| |
| |
Hub -------------------------
|
|
Workstations/Server



So basically The IDS would be setup as following, eth0 would take the conection from the router and bridge it straight onto eth1 which goes into the hub. eth2 would be plugged into the hub and used as a connection the IDS.
eth0 and eth1 would operate at Layer 2 so neither would have an IP address or be known to the network. eth2 would opeate normally with an IP address and be used as the connection to the box.

Sorry its a bit long winded but hopefully it gets the idea across. Any suggestions please just say.

Cheers
