FWIW, for AIX, Linux, SVR4, Solaris, and other modern OSs, the names are assigned sequentially, starting with en0, so as to not require script or other configuration changes. The (small) risk in this is if you were to blindly change slots on cards, configure new hardware, or otherwise ignore probe ordering, and thus confuse two cards (say the inside and the outside of your firewall). This is generally a one time possibility at install or upgrade time, and seems to be worth the risk, since the inside and outside numbering are going to be different anyway, and it will just not route packets at all, rather than compromising your security, except under rare circumstances, where you have a strange setup AND you rearrange your hardware. In any case, most people buy two of the same type of cards, so you already have the same problem with distinguishing de0 and de1 following a card replug-fest. > ATM on the other hand, (if I understand it correctly), is aware of its limits. > It hopefully would not allow itself to be oversubscribed.

ATM has other problems; remind me to tell you, when we are in the same room, and you have an hour or so to kill. 8-).
