>Description:
Changing certain ipf/ipnat kernel variables during boot results in a Device busy.

ipf/ipnat tunables must be made when ipf/ipnat are inactive.  Since /etc/rc.d/ipnat is processed before /etc/rc.d/sysctl, variables set in /etc/sysctl.conf for ipf/ipnat are not applied.

>How-To-Repeat:

>Fix:
Adding sysctl to the REQUIRE list in /etc/rc.d/ipnat appears to be a suitable fix/workaround.
