This is part of a "tried fix". I noticed while I was in Switzerland the Swisscom adsl+wireless router gave me a all ones broadcast thus I figured what the hell, might as well try that. So I had configured my bridge with this broadcast address. I deleted the broadcast argument from ifconfig now and matched dhcpd.conf accordingly, but no changes in behavior. -- Mel
