-> BTW, please cc netdev or myself if you are addressing me. This email was -> just forwarde by someone else to me - I am not on linux-net. You seem to -> have trimmed down the CC list. -> You should join the list and the quit when you are done. Otherwise, like with this email I get multiple copies of it. -> I read this a few times and still didnt get it: -> Why is it that people using 1918 addresses are affecting you? -> Does using 127.x help you because you assume _nobody_ else would be using -> 127.x addresses? I am in a chassis. I need a way to do interface card communication. Even if those cards are exposed to the outside world. -> I am assuming you want this address for some internal network whereas the -> external contains some routable addresses? -> Yep. -> > So I have this working in my products now. I had to do something a bit -> > different in that I want a "special" 127.xx.xx.xx range to be sent out -> > on the wire. So here is what I did. -> -> [..] -> -> Seems you did too much.
