Here is my rc.conf entry for this interface: I just wanted to report that after a reboot, things seem to be working properly and I cannot reproduce the problem. I had also rebooted my cable modem when this shutdown occurred, so it's entirely possible the SMC D3G cable modem was at fault. If I can reproduce the problem, I'll post additional information/details, but for now it seems the problem was transient. Thanks! Josh
