I just had this bite me (hard) on a gateway machine that "disappeared" offline from the Internet. A flap on the interface that appears to have come from the attached cable modem dropping the link to the unit momentarily resulted in a rebind BUT the address never got re-assigned to the igb0 interface. A manual ifconfig down/up fixed it, but this was a quite-severe incident because it left the external connection completely invisible -- if there had been nobody available on the "inside" to do that manually..... I'm on 12-STABLE r343809 on the specific box in question. -- Karl Denninger k...@denninger.net <mailto:k...@denninger.net> /The Market Ticker/ /[S/MIME encrypted email preferred]/
