I have m0n0wall setup on a PC with (3) nic's, wan/lan/opt. During
initial install, I had all three hooked up to respective devices.

Wan to border router
Lan to switch-1
Opt1 to switch-2

I am currently not using Opt-2 yet, although the network is configured
in m0n0wall. Do I need to keep the CAT-5 cable for Opt-1 connected to
a spare switch, or can I un-plug it ?
I want to use the switch for setting up a backup m0n0wall box.

Thanks
