Multiple Nics, No Connectivy <Guru Question?>

[Xanathar]

I want to have lets say 4 Nics inside of a computer, however I dont want to be able to connect in between them. I guess the easiest way to phrase this Is i would like to be able to set a source for a ping packet <lets say IP .1 binded to NIC 1> and then ping IP .2 binded to NIC 2, However I do not want to have the OS just ping itself, I want the packet to travel out of Nic 1, and then into Nic 2. Therotically being able to test the thouroput of a switch I placed out there, or with a cross over cable checking the max specs of a card, or even just for connectivity purposes of testing a crossover cable with 1 machine.

And what OS is this computer running?

9x NT or Win2k any of the above if needed.

I would think 9X is out. NT or Win2K might do source routing for you, but I wouldn't know.

If you're just trying to test firewall rules and need to source an address you could use hping. Then you wouldn't need to have 4 cards in the computer at all.

On a unix box, you could easily do something like this but I don't know how on M$.

If you have access to a PIX or a Lucent(Ascend) TNT, you could just configure some of the extra interfaces to do this.

on pix, define your if_name and address then
ping if_name address

On TNT
ping -s 10.10.10.1 198.6.1.1 (hmmm.. I think its minus s.. been a while)

Ack! Ascend Max TNTs! Ack! Ack! Ack! Why must they be so danged different! I don't like those things.

I can deal with the Ascend Max X000 series stuff, not that I like it, but I can deal with it. Then you have the TNT stuff, which has to be COMPLETELY different. Arghhh!

The company that's buying my company wants us to eval those units in hopes of replacing the 3Com TCs we use for analog and the Cisco AS 5300s we use for ISDN. NOT!

The first one we got wouldn't even pass self test. Yeah, I'm impressed.
