What you probably need is to do a "pf resync"; rc.d/ppp already does
this, but too early for named. Doing it after named is running is
probably not sufficient as there is no guarantee that ppp has
established a network connection. 

I wrote a script that waits until it can ping external hosts, and then
does a resync:


#!/bin/sh
#
# PROVIDE: networkwait
# REQUIRE: named
# BEFORE:  ntpdate

. /etc/rc.subr

networkwait_enable=${networkwait_enable:-"NO"}
name="networkwait"
rcvar=`set_rcvar`
stop_cmd=":"
start_cmd="wait_network"


wait_network(){
   if [ "$networkwait_ping_hosts" ] ; then
      host_list="${networkwait_ping_hosts}"
   else
      # No hosts supplied - use external nameservers
      host_list=`awk '/^ *nameserver/ {print $2}
        '< /etc/resolv.conf | grep -E -v '^127\.0+\.0+\.0*1'`
   fi
   echo -n "Waiting for network access ... "
   while true ; do
      for inet_host in $host_list ; do
         if ping -nc1  $inet_host 2>&1 > /dev/null ; then
            echo "ping to ${inet_host} succeeded."
            # Re-Sync ipfilter and pf in case
            # they had failed DNS lookups
            /etc/rc.d/ipfilter resync
            /etc/rc.d/pf resync
            exit 0
         fi
      done
      sleep 5
   done
}

load_rc_config ${name}
run_rc_command "$1"
