[-- Attachment #1 --] Thanks, Something I notice: Nov 29 11:36:00 <14.6> hermann kernel: sysctl: oid 'net.inet.ip.fw.default_to_accept' is a read only tunable at line 98 This setting needs to go in /boot/loader.conf, not in /etc/sysctl.conf. A bigger thing is that in the output you sent me I don't see dhclient being started. Are you sure your /etc/rc.conf is correct? Can you send your /etc/rc.conf? Regards, Ronald.
