Tiger,
As per my understanding, NICs in "promiscuous mode" listen to all network traffic, not just that directed at the interface. This will put a higher load on the processor and bus.their NICs must run in promiscous mode - which takes its toll on the
NIC itself.
this one i don't get. what kind of toll does it take? will the NIC
tend to fail
faster physically because it's running in promisc?
So basically, not all NICS can be used for example as a bridged device, since you need quality NICS (large buffer size) if you need to run them in promiscuous mode. ex: The TI ThunderLAN chip is a poor NIC wherein 3COMS are quite adequate for the job.
As far as I am concern, a gigabit NIC card on a 64bit PCI will par if not out-perform any available firewall appliance today.
