Ops. I need to assign IP address to interfaces and also activate IP
Forwarding, because the same sensor machine will be the firewall between
different network segments (that is whay this solution is cheaper, but
also less secure...). I'm thinking in switching back to the layer2 or
layer3 switch and try to convince my boss to spend more money :(

Anyway, it is a departamental network, not a corporate one, so I need to
balance the cost of the solution to the cost of the information to protect.

Thank you very much for your advice.
Sergio
