Just a couple more questions on the migation to ipfw and
this much should be done. Do I need to write for the "out"
rule in ipfw, "out xmit via dc0"? Similarly for the "in"
rule, do I need the "recv"? I thought I'd better check
with the list for input on this.
How close did I come with these 6 lines?
thanks very much!!
