Compiled it taking all the defaults on new features. It boots just fine but has fatal ip_tables errors over and over missing this item. Cannot connect to internet. Any ideas? Do I need this and why? Google had something about setting: modprobe ip_conntrack_ftp ports=21,2121 if compiled as a module. So I set the previously unset constant=m and am recompiling. Where would I specify the modprobe arguments?
