 Well this is what i think would work ( i stand to be corrected) it's all down to your firewall
you could deny any traffic/services/ports to any service on your 3rd interface in your firewall rules and allow what traffic/services/ports on the rest of the interfaces ..IIRC you have somewhere in ipfw where you specify your interfaces. This is a terse explanation so i hope it makes sense
my 2 cents :)
ciao

third interface except for a few protocols. I'm not doing NAT. How
would I go about this?
