# This Shell scripts used to NAT by iptables, to make wlan0 as the downlink device
# and set the uplink device as eth0/ppp0, it will be called by crond

DOWNLINK_DEV="wlan0"

#可以改为ppp0

DEF_UPLINK_DEV="eth0"

#使能profile和ifcfg-wlan0文件
source /etc/profile
source $network_cfg_dir/ifcfg-$DOWNLINK_DEV

#在ifcfg-wlan0文件中有设置是否使用AP模式，如果没有就会在这里退出。
if [ $WORKMODE != AP ] ; then
   echo "$DOWNLINK_DEV doesn't work as AP mode, exit now..."
