I just upgraded from Core update 126 to 147. I have a new behavior that is becoming unacceptable. Every time my DHCP lease is up on the red0 interface, all connections are dropped. Part of the problem is that my modem is currently leasing IP addresses for on 600 seconds instead of the configured once a day.
Since my external IP address has not changed in several years, I tried to change red0 to static. Now in System->Home the interface stays up, but in /var/log/messages I get:

I used TCPDUMP to verify the /var/log/message. And yes my modem failed to renew the DCHP lease. But why am I DHCPing on a Static Interface? How to I work around a misbehaving modem?
